My only option was to go down to the casino in which oxygen is constantly pumped and you can smoke and drink espresso or whatever tickles your fancy. This was a bit of a deal breaker as I was there to work. The only serious drawback was that for some inexplicable reason I couldn't get WiFi in my room.
I stayed in one of the premium rooms on the 10th floor, which was 500 square meters of heaven. It was my first trip to the US so to use the phrase 'uber overwhelming' is a serious understatement. If you are into gambling and burning money you'll have a blast. I stayed at Pechanga for 8 days and generally was impressed, however, there were a few things that weren't cool.
