Anyone know how much room is in the POP King room? We are 2 adults and 2 children - one is a kicker so we want the air bed option for him as no one wants to share...but we can get the 2 boys on a queen size one - but not sure if that would fit. or two twins? the youngest (5) can sleep with us - but after all the walking at the Parks everyone needs a good night's sleep..
