Bill's is awesome in a weird kind of way. The rooms are surprising good, but the bathroom sucks. How much are you going to spend in the bathroom seriously. Ladies - sorry, this won't work for you if you are high maintenance or take three hours to get ready.
Drinking the casino margaritas for $2 are good, they were better when they were $1. I'd stay here in a heartbeat. I've stayed at most of the Las Vegas properties (work) so this is a solid place.
Spring/Summer tip: You can use the Flamingo pool because Bill's doesn't have one.
Enjoy!
