Hi, Terese!
First, I have to gush over
Boulder Ridge Villas at Disney's Wilderness Lodge. I love Wilderness Lodge so much, and I always feel like I'm getting two vacations in one. You get the sunny central Florida with palm trees you are headed to
Walt Disney World for, but then you also get the Pacific Northwest, with it's rustic feel and majestic evergreens. It lets your vacation stay magical both at the park and at the resort!
The one bedroom villas at Boulder Ridge do sleep four guests, and there are only two options for sleeping - the king sized bed in the bedroom and then a queen size pull out sleeper sofa. There is the option to bring an air mattress, and you will also need to provide your own linens for that, but there is space for it so that it's not too intrusive if anyone has to get up in the middle of the night to get a drink or anything.
Something you may want to look into is a a different
accommdation at Boulder Ridge. The Deluxe Studio, for example, has a queen sized bed, a double sized sleeper sofa, plus an additional single bed that pulls down like a Murphy bed from the wall. That bed is a little smaller, so defintely for the tiniest among you, but at least it is a separate sleeping space.
There are also other 1-bedroom villas with a third sleeping option.
Disney's Animal Kingdom Villas have a pull out chair that acts as a twin bed in the 1-bedroom villas.
Have a wonderful vacation!
