"Room only" reservations offer better terms for cancellation and payment dates than vacation packages booked through the Walt Disney Travel Company (WDTC). Here is an outline of the differences:
When booking a "room only" reservation, you are subject to very few restrictions:
You must pay one night's room rate as a deposit within 14 days of reserving your room. (Except when booking online at DisneyWorld.com, in which case full payment is required if reserving within 45 days of arrival.)
Final payment of the remainder is due at check-in. (Except for online bookings; see above.)
You can change or cancel your reservation without penalty up until 5 days prior to check-in. (6 days for online bookings.)
When booking a vacation package through WDTC, you will be subject to the following rules:
You must pay a $200 deposit within 14 days of reserving your package.
Final payment of the entire remainder is due 45 days prior to check-in. You have to pay in full right away if you are booking less than 45 days in advance.
You can change or cancel your reservation without penalty up until 45 days in advance. From 6 to 44 days in advance, there is a cancellation fee of $100. If you cancel 5 days or less in advance, you pay a $200 penalty.
Any changes that result in a rate change, such as applying a discount code, reducing number of days and/or changing to a differently-priced resort, made 45 days or less prior to arrival, are subject to a $50 fee.
Beware - WDTC usually adds nonrefundable
travel insurance to your package by default. If you don't want it, tell them while you are making the reservation. Once you hang up, it's too late. You can add the insurance later if you wish, up until your final payment is due. You can also buy travel insurance directly and usually save some money that way.
Airfare added to your reservation is also nonrefundable. It's hardly ever a good deal, either. I strongly advise booking airfare separately. Visit the Airfares page for hints on how to save on airfare!
