We will be traveling with our two boys, ages 20 and 17 next year. They are too big to share a queen bed, let alone a double. As I'm planning out our 10 day PCH vacation, we will be staying at approximately 4 different hotels. Some of them I don't mind getting two rooms, but where we will only be staying a one night/two nights, it would be nice to share a room. Do you find that the hotels will bring a spare bed? We don't have to do this, but it would be nice to cut costs a few nights. If not, I had even though of buying a blow up mattress and each boy can take a turn those nights we decide to share a room.
