We are a family of 5, too. Our children were 2.5, 4, and 12 during our May visit. We stayed 5 in a room at AKL (8 days) and CSR (2 days) with no difficulty or crowding. At AKL, our 2.5 yo and 4 yo slept in the top bunk; while our 12 yo slept on the bottom. At CSR, I fell asleep with the younger children while dh and older ds went to DQ. Dh and 12 yo ds ended up sleeping together. We have one more family trip planned before we have to go to 2 rooms. We haven't done 2 rooms since we stayed at CBR a few years ago and did NOT get connecting rooms. Ugh!
