15 Hidden Fees Americans Often Face on International Trips

11. Single Supplement Surcharges: The Solo Traveler's Unwanted Plus-One Fee

Traveling solo? Many tours, cruises, and even some hotel rooms are priced based on double occupancy. If you're alone, you might be hit with a "single supplement" – an extra charge to cover the presumed missing second person. The Ingenious Part: It effectively penalizes solo travelers for not sharing costs. Sidestep it: Look for tour operators or cruise lines that cater to solo travelers, offer roommate matching, or waive single supplements during promotions. Some smaller guesthouses are also more solo-friendly.
