Just wanted to let everyone know, what's going on for Memorial Day and possibly 4th of July is a Group Reservation, not a Grand Gathering.
For a Group Reservation, you need a minimum of 10 Sites/Rooms (not people) over a set period of time (although folks can book before and after) and folks can book for a portion of the dates if you have more than 10 Sites/Rooms. This is handled by a completely different division of Disney Reservations and someone actually has to sign a contract. With a group reservation, everyone has the same type of site, and you are generally guaranteed to be in the same loop. There is generally a pretty good discount associated with booking a Group Reservation, you can also get discounted Disney Tickets with a Group Reservation.
Hope that splains things!!!!
