Whenever I call WDW they always reverify my home as well as the cell number. I was calling from my husband's cell and they wanted to add that as well. It's a shame that people want to double book and take up 2 reservation. Some might cancell, some might get caught and have none, but all the same many of us are trying to just get ONE! Yes, there may be some reservations available at the hotels when you arrive, maybe they are the cancelled at the last minute reservations, maybe WDW is just keeping some since it is nice to be able to eat at one of the WDW restaurants when there. I have visited WDW MANY times, only since the
free dining have I had to make reservations prior to arrival! I hope the double bookings are kept under control. WDW usually asks me for the reservation number as well as my phone number, so that might be a way to stop those using my brother's, sister's and who knows phone number to double book.
