There are 7 of us (me, dh, ds13, ds4, ds2, dd12, dd4) and we had 2 rooms that were linked under 1 reservation number and we were all on the dining plan. We always sat together at restaurants and funny enough most rides can accomodate 3 people in one seat too so there was never an odd person. (other than the roller coasters, which are usually 2 seats side by side).
