That is where the laundry is. There's a vending machine around or in the room too as I recall. Or was. Not certain if it's survived or not.
It all looks great I think Granny! Didn't compare to the old to see if the rooms numbers match or any of that. One thing - I know is that GrandCalifornian matched up similar colors for the CCV map to the old VWL map to give some consistency to DVC map making. Maybe you would want to use those too?
I would suggest keeping the colours distinct.
The CCV map has a couple colour pairs* that are so close to each other that while it may be consistent with DVC map making, it is almost impossible to tell different but such closely coloured categories apart.

*ETA: the studio pairs are the issue, distinguishing between tub/no tub is nearly impossible even if they were side by side because the colours for each pair are nearly the same.
