Hi Lennie,
Walt Disney World actually has a link to help out families of 5; just click
here.
Port Orleans Riverside is also an option as it has rooms that sleep 5, but the 5th bed is a trundle bed, so it wouldn't sleep an adult or a large child well.
With the dates of your vacation, the
Art of Animation resort should be open, and I think it looks amazing! And with the family suites, I think you'll find lots of room to spread out.
Another option is to book connecting two rooms at any of the resorts.
By the way, if you haven't ordered your free planning DVD, you may want to do that by clicking
here.
Thanks for the question; please let us know if we can help again!
