They changed it at some point after I booked. When I booked, it said 5, and I made sure to enter 5 guests on Marriott.com. I was surprised it came up as I know 4 is often the limit. But I have a confirmation that says 5, and interesting enough, the associate I chatted with confirmed that 5 people are allowed, but a rollaway is not. That statement really makes no sense, because I think it is reasonable to assume that if you are allowing 5 people, all 5 need a place to sleep.
