6door74 - my comments were directed at the OP's choice. I think there are valid reasons for having the extra bathroom (my dad used to go to dog shows with his female dog handler and the extra bathroom would have been much nicer for her).
But, again, if the choice is one bathroom with outside access and a bunkroom. And the family will be camping at campgrounds (versus always at RV parks), I would take the outside access over the bunk room.
If the OP is staying primarily at RV parks, then it's probably safer to go with the bunk rooms because many do not allow tents.
