FREQUENT FLYER GLOSSARY
What are adjoining rooms?
Adjoining rooms are two or more hotel rooms positioned next to each other, typically sharing a wall, without an internal door that lets guests walk between them; a connecting room is one that also has that door. Hotels sell rooms by category, such as a king room or a twin, so an adjoining or connecting pair is normally a request noted on a booking rather than a room type a guest can reserve outright. Marriott Bonvoy, the loyalty programme used as the official example on this page, sets the booking, earning and redemption terms for stays at its participating properties in Program Rules updated in October 2026 [2].

Key takeaways
- Adjoining describes position: rooms next to one another. Connecting describes a door: an internal door joining the two rooms.
- Every connecting pair is adjoining, but most adjoining pairs do not connect, so the two words are not interchangeable.
- Neither is a bookable room type. A reservation covers a category such as a king or twin room, and the hotel works out any pairing from what is free on the night.
- Families who want to move between rooms without stepping into the corridor should ask for connecting rooms and use that exact word on every reservation.
- Marriott Bonvoy credits a member's stay across a member's own room and up to two additional guest rooms booked for the same check-in and check-out dates [2].
What is the difference between adjoining and connecting rooms?
Adjoining rooms are neighbours: they sit side by side, share a wall or an entrance area, and are still sold as two separate units. Nothing in that arrangement lets a guest walk from one to the other without using the corridor and the main door of each room.
Connecting rooms add one feature — a door set into the shared wall, released by the hotel when the pair is given to one party. For a parent, that door is usually the entire point: a child can be settled in the next room while an adult stays up, without leaving the room to check on them.
Adjoining is therefore the broader word and connecting the narrower one, and hotels do not always use them with the same precision. A request that says only "adjoining" can be satisfied by two rooms that never connect.
| Feature | Adjoining rooms | Connecting rooms |
|---|---|---|
| What it describes | Position: rooms next to each other | A door between two rooms |
| Internal door | No | Yes |
| How it is arranged | Requested, subject to what the hotel has free | Requested, subject to what the hotel has free |
| Typical use | Groups and families who simply want to be near each other | Families, carers and anyone who needs to move between rooms without the corridor |
Why are adjoining rooms a request rather than a guarantee?
The number of connecting doors in a building is fixed. A property can only pair rooms that physically connect, that are free for the same nights, and that match what each guest has actually booked.
Room allocation usually happens at the property close to arrival rather than at the moment of booking, and it keeps moving as cancellations, late checkouts, maintenance and upgrades reshuffle the house. A request can be logged on the reservation and read by the front desk, but the pairing is only settled when the keys are issued.
That is why a confirmation email showing "adjoining rooms requested" is a note, not a promise. Guests who need the connection should treat the answer at check-in as the real answer and arrive with a fallback in mind.
How should families ask for adjoining or connecting rooms?
- Use the word that matches the need. If the requirement is an internal door, write "connecting rooms". "Adjoining" asks only for rooms side by side and can be met without any door.
- Put the request on every reservation in the group and quote the other booking's confirmation number, so the hotel can see that the bookings belong together.
- Give the reason and the ages of the children. A front desk working with a full house has more to act on when it knows why the pair matters.
- Book the same room type for both rooms. Pairs sit within matching categories, so mixing a suite with a twin narrows the options before the hotel starts.
- Ask for the request to be noted in writing — a line on the confirmation is enough — and repeat it at check-in, when room numbers are actually assigned.
- Have a fallback ready: rooms on the same floor, rooms across the corridor, or a single larger unit if one is free.
Where the request is made matters too. A note typed into a third-party booking site does not always travel through to the hotel's own reservation system, while a note added through the hotel's own channel is easier for the front desk to see; hotel booking channels sets out the difference between booking direct and booking through an intermediary.
What does Marriott Bonvoy say about booking more than one room?
Marriott Bonvoy is the loyalty programme of Marriott International, Inc., and its Program Rules were updated in October 2026 [2]. For a family taking two rooms, the rules matter most for crediting rather than for door configuration: a member staying as the registered guest earns on their own folio and on up to two additional guest rooms with the same check-in and check-out dates, provided the member gives their membership number, stays in one of the reserved rooms and pays the charges [2]. Rooms without matching dates, or rooms paid for by someone else, fall outside that arrangement [2].
Where a family needs space rather than an internal door, Marriott's redemption pages describe point upgrades and paid upgrades to a better view or a larger suite; these are applied during booking and are available at select hotels and resorts [4]. A suite is a single unit, so it suits a household that would rather share one space than occupy two rooms next door.
Exceptions and limits
- Status and points do not create a door. An upgrade can move a guest to a larger room or a better view at participating hotels [4], but the building's layout stays as it is, and a connecting pair still depends on what is free.
- Occupancy rules come first. Limits on children, extra guests and maximum occupancy decide which rooms a family may share before any pairing is discussed; see hotel family stay policies for children and extra guests.
- A connecting door works both ways. Sound and light pass through it. If the second room is empty or occupied by someone else, check that the door is closed and locked.
- A reservation secures a room, not a room number. The guaranteed room entry explains what a guaranteed booking covers, and a hotel room block holds a group of rooms without fixing individual door configurations.
- Small properties have few pairs. The smaller the building, the fewer connecting options exist, and the earlier in the day a family checks in, the more choice the front desk still has.
Frequently asked questions
Are adjoining rooms the same as connecting rooms?
No. Adjoining rooms are next to each other; connecting rooms have a door between them. Every connecting pair is adjoining, but adjoining rooms often have no internal door at all.
Can a hotel confirm connecting rooms before arrival?
Usually not, because the pairing depends on which connecting rooms are free for the same nights, and those rooms are assigned close to arrival. The request can sit on the reservation, but the answer normally comes at check-in.
How should I phrase the request for a family with young children?
Ask for "connecting rooms" by name, give the ages of the children, quote both confirmation numbers and ask for the note to appear on both reservations.
Can I earn points on both rooms of a pair?
At Marriott Bonvoy, a member as registered guest can earn on their own room and up to two additional guest rooms with the same check-in and check-out dates, provided the member gives their membership number, stays in one of the rooms and pays the charges [2].
What if the rooms are not connecting at check-in?
Ask whether a move is possible later in the stay, and ask what else is free — rooms on the same floor, or a single larger unit. Availability is decided by the hotel on the day.
