We have a 3bdrm house and set it up for 2 bedrooms with Queen beds, and the smallest bedroom with a trundle bed. Initially, the reason for that was the small size of the bedroom, however, it has turned out that we have groups of 3 or 4 and they aren't all married, so they use all 4 of those beds. So, have two twin beds, so multiple people have their own bed, has turned out to be what the Guests wanted (in general). That arrangement seems to have worked well for our Guests. We've been surprised how many of our Guests of 4 in the group have not been two couples, but maybe a couple and 2 non-couples, or even 4 people wanting to sleep individually. Good Luck!
