Overall happy with our stay. The set up is nice and includes all amenities you need, plus the hot tub is a nice bonus. Everything was clean and heaters were on when we arrived. It is a bus so there's not much head room if you're taller but there plenty of room to move around inside.
The only issue we had is that one of the heaters would not stay on. The power strip that it was plugged in to would turn off every 20-30 mins. There was another heater which was enough to heat the sleeping space so it was not a big issue, more of a minor inconvenience.
