All prices are per person in U.S. dollars. Regular Rates vary for each land package and river cruise package (collectively "vacation package") itinerary based primarily on when you book, when you travel, room configuration and room location (in the case of river cruise packages). Once your deposit is received by Adventures by Disney Travel Services, Inc. ("we", "our" or "us"), your vacation package price is guaranteed for your party, except where price increases may result from increases in government taxes or fees. Guests added to your party after initial booking will be priced at the then-prevailing rate. All prices are subject to change without notice. A single supplement applies; please call a Vacationista for details. Room configurations are subject to availability; please see "Note on Accommodations" in the corresponding description of each vacation package for rooming information. Child rates apply to Guests under age 12 at the time of travel. All Guests under age 18 at the time of travel must be accompanied by a parent or legal guardian in the same room.
