Hi:
I think you are allowed 5 in a room, they may charge you an extra $25.00 for the third adult.
We love the poly, you get two queen beds, plus a nice size daybed. It is the size of a regular twin bed. The rooms are big enough for all of you, also the bathroom is a nice size.
It is nice to have the opportunity to either take the monorail or boat to magic kingdom.
The grounds are so beautiful if you like plants and trees etc.
Have fun,
Deb.
