We always booked 5 in a studio until our oldest got married and left us

.
We were all on reservation and all got keycards with our names. I was told you can have one over stated occupancy in all rooms except AKL values. They will not provide bedding or towels, but often housekeeping left us extra towels.
At the BWV they have a studio that has a daybed and they usually gave us one of those rooms. The thing is not full length and does not look comfortable, so we would always bring an airbed which we set up by the door so we could easily get to the bathroom without bumping into it.
It was not too crowded--I miss those days!
