How to handle a cruise solo supplement

What does a solo supplement pay for?

A solo supplement, as used here, is the extra amount a cruise line may charge when one traveller occupies a cabin that is priced for two people. Ask the line to confirm what the supplement covers on the sailing you are considering, including the total for one occupant and whether the supplement is shown as a separate line.

Holland America Line's site includes a “Find Your Cruise Vacation” page with cruise-length and destination navigation [8].

For a specific sailing, ask the line to confirm the supplement, any waiver condition and the total for one occupant before comparing quotes.

Solo cabin or supplemented double?

Ask the line to confirm four points for the sailing:

• Cabin grade and position. Confirm the grade and where the cabin sits; see cruise cabin categories and locations for the questions to ask.
• Total for one occupant. Ask for the total, not the headline per-person fare, and whether the supplement is inside it or shown as a separate line.
• What the fare includes. Compare dining, drinks, gratuities and transfers on the same basis.
• Fare conditions. Ask for the deposit, change and cancellation terms that apply to the solo fare on that sailing.

How do solo travellers earn loyalty credit?

Royal Caribbean's FAQ lists Crown & Anchor Society Loyalty Program as a topic [2], and Holland America Line's site lists Mariner Society [8]. Use those entries to find the programme page, then confirm the rule with the line.

Ask whether credit is awarded per cabin or per traveller, and whether a reduced solo fare earns the same credit at the same cabin grade as a double-occupancy booking.

For loyalty programme background, see the cruise loyalty programmes guide.

Limits on a solo quote

• Confirm the total for one occupant. Ask for the total, not only the headline per-person fare, and whether the supplement is shown as a separate line.
• Programme listings. Royal Caribbean's FAQ lists Crown & Anchor Society Loyalty Program [2], and Holland America Line's site lists Mariner Society [8].
• Check the sailing, not the line in general. Confirm single occupancy, the total for one occupant and the fare conditions with the line for the specific departure.
• Confirm loyalty credit. Ask the line how a solo booking is credited.
