We are a family of 5 and usually do one hotel room, it’s always been fine, especially at Disney. My kids can hang until the late evening (9, 7, and 4) so we usually stay until park close then all head back and go to bed at the same time. They’re out in minutes and DH and I play on our phones or whatever until we fall asleep. Though as they get older we will look into doing more suite-style rooms for more privacy.
