Really nice rooms. Although the original tower is older, it is maintained very well. Staying in this building can potentially save a ton of walking. The newest rooms are really far from the lobby and the main casino. Several years ago I asked for one of the 'new rooms'. I had no idea that I'd have to walk to the 215! And when my room key didn't work at 4am, it was waaay easier to use the house phone and wait in the hall than walk all the way to the lobby. All of their rooms are very nice though. Nice beds, nice amenities, and a very upscale feel.
The casino has definitely improved over the years since they first opened. Added a poker room, expended the casino, and added an extra pit. AND they recently brought back the Grand Cafe! ----- really good breakfast. Their buffet is the best of all of the Station's buffets. They dropped the crab legs when the prices were lowered about a year ago, but for $14 the dinner is well worth it.
All in all GVR is still a really nice property.
