It is a floating Casino and is located on just one deck of the ship. There were maybe a dozen or so table games and maybe a couple hundred slots.
Uncle Jake's BBQ Buffet shared the same deck as the Gambling area, so you can tell it was quite small.
The gambling area was nice and clean. The dealers at the table were very friendly and professional. While smoking was allowed, I was not super conscious of the smoke, so the ventilation was good.
