Hi, we are traveling to WDW nest year. We have a new son-in-law bringing our party up to 5. I've looked at several different room types and wonder if anyone can give some advice. We've stayed at the FW cabins with 6 and that is an option, but we always like to try a new place so that's on the back burner for now. I know several resorts "sleep 5" but really is that extra fold out chair/couch usable for an adult? Thanks for the help
