It turned out that there was one of the "Apartment" Rooms available up until the Friday the 20th, so I reserved that room from Sunday May 15th to Friday May 20th. We would check out on Friday and head back, which is probably for the best anyway.
This moves the schedule up by one day. Instead of arriving at Deal's Gap on Monday we would arrive on Sunday.
The room has two bunk beds and two futons.
