I'll go first, I would love either an apartment/room that is built and able to be toured. Almost like this is what it would be like to live on Main Street U.S.A. Or maybe a hotel outershell structure. You know, not an actual hotel but the appearance of one. Cast members playing along how it is impossible to book and how it has been booked for years. Even have characters rushing to check into a room passing people to the front desk aka the cash register of a shop.
