Rantakioski - Seaside stall

My work for the hotel is (and has been for some time already) at a standstill because I'm trying to figure out how to make the elevator doors. I might have to re-make the low staircase [in the lobby] as it seems that I didn't leave enough space for the doors, move the elevator or, just add a regular door with a sign saying 'Aux chambres'.
As it's summer, I thought I'd showcase one of my summer-themed scenes again: the Seaside stall
