Good action, good buy in, short wait times, and free beverage fountain (awesome selection)! The only negative is that you have to drive from the main casino to the "smaller casino" which had the card room. The smaller casino was a bit more dingy and run down than the main casino.
I went on a Friday and there were 25 people ahead of me for the 1/3. I walked around for a bit and sure enough I was seated in 30-45 minutes which was not long at all.
I drove from Orange County (1.5 hour away) to experience the Morongo, and I was overall satisfied with their room.
