The reason I stayed here was as part of their Thai Visa Run Program advertised on their website. Excellent value for money and no hassles (recommended). The location of the Hotel is outside of Savanaket, and there's nothing much around. The 3 time daily buffets were accurately described by the previous reviewer. You might have a higher chance getting food / place to sit on weekday.
The room I stayed in was in the same building as the casino; it was clean and spacious and well appointed. The only real downside was a rock hard mattress and slowish (but useable) internet speed. There was a good selection of channels on the LCD TV.
The aroma therapy massages at the Spa are excellent - as good as any I've had in Bangkok and at a reasonable price.
The Casino was swarming with Thai, up-country gamblers. In fact most of them seemed to have come straight from the farm ... no wonder they keep asking for handouts from the red-shirt government.... It's quieter at night.
If your are merely a traveler, my recommendation would be to stay in the town at one of the guest-houses, though Savannakhet is really only worth a couple of hours strolling around the old part of town. No reason to stay at the casino.
