I don't think I have ever booked anything other than 1 adult. Almost every time I travel for personal reasons, I have anywhere from 2 to 8 in the room. Obviously 8 is only at the two room suites with fold out sofa at Staybridge.

Edit -- I should also point out that when we check in, we're all at the front desk. We don't sneak the kids in or anything like that. lol
