A question for those Opponauts with more than 2 children. I know you're out there.

I'm booking rooms for our family vacation this summer (Austin, Carlsbad, Roswell, Las Cruces, San Diego, Flagstaff, Clovis, home). I've got me, my wife, three kids. If I put "2 adults and 3 kids" in the hotel reservation system, the vast majority of the rooms come back as "exceeded occupancy for this room." I'm already planning on getting an inflatable mattress for one of the boys to sleep on, but I'm just leery about claiming 4 occupants where there are really 5. Should I care? Will the hotel care?
