we are booked at the dolphin and hoping to stay there, but finances have recently changed and had to book at the pop century as well in order to be able to make sure we can still go to wdw. If dolphin doesn't work out, pc here we come. I asked that we get a quiet building...even the cm couldn't help us out on the phone, she didn't have access to a map or know what that would be but indicated the request on on the resv. I don't know that they are even sure which buildings are 'optimal' yet.
