most DISers here have had to "build" their reservations a couple of days at a time because of whats available...Ive not read a single post that said they were required to change sites....but they do have to go and re-check in at the end of the 1st reservation. If Im incorrect, Im sure they'll chime in quickly.
I'll start a new thread and check it out, don't want to high-jack Disney4dan thread them being new and all.
