as for the house/hotel question, maybe a lean-to for one of those. like the one behind the ladyfoot locker.
This idea is in the running as well. What if lean-tos were the houses and a clubhouse or shanty was the hotel? Does that make sense?
There was high-school bully Troy Dershman's clubhouse in Coach Fannel's (if I have the name right) backyard.
What about the Aquamansion?
