Which, if any, of the Restaurant.com restaurants are in WDW? I'd like to get some of the gift certificates but I want to make sure we can get reservations to the restaurants first before getting the GCs.
Read the restrictions on the swan and dolphin ones carefully. Some of them are very specific, have high minimum orders (this is especially important if there's only 2 of you, as they tend to exclude alcohol as well) and/or can only be used for dinner. For some of them, you'd be better off having a late lunch than using a restaraunt.com certificate and paying dinner prices.
