Personally I think I would have gone 100% bonkers at the training hotel for 4 weeks. I found a room in a nice house/small crashpad owned by a 765 FO and enjoyed being able to cook healthy meals, kill some Sweetwaters with the roommates, walk in a neighborhood I didn't have to worry about getting shanked, etc. And yeah, saved about $1400 to boot. There are some good alternatives out there, just ask around, especially among the people 3-4 weeks ahead of you.
FYI: You can still come to the training hotel for free beer & wings on Weds nights!
