I don't recall being able to take the night off and sleep in a hotel during SERE. It was a long time ago, but that's something I think I'd remember. When did you go through SERE? Did you stay in a hotel at night?
S.E.R.Eis Survival. Evasion. Resistance. Escape .
There are of course some hotels around where some SERE skills are required. The Silver Rock in Barbados comes to mind.
And even in some excellent 5 star luxury hotels I have ended up spending the night out in a location such as a rocky outcrop, without any shelter, with no food and water in the middle of a island in the hotel pool.
