My wife, two daughters, and I oftentimes use Las Vegas as a stop-over on the way to Utah or Northern Arizona or as base camp from which to visit other parts of Nevada. I mention this to emphasize that Boulder Station served well as our base camp for two nights and not as our vacation destination. If you are looking for the glitz and glam of Las Vegas in your hotel choice, move on to a more expensive 4 or 5 star location.
Our room with two queen beds met our needs. It was clean and adequately roomy, and it had a decent TV we barely used. The room temperature stayed comfortable both day and night. Before booking our room I read previous travelers reviews here and on other sites, so I knew to expect noise from other rooms. I brought ear plugs, so I did not hear the noisy neighbors in the room next door who arrived late and spoke only in "outside voices" (as my first grader's teacher would say). I'm the light sleeper in the family, but the following morning my wife and older daughter told me about all the commotion I missed. I found it odd that I couldn't access the hotel's Wi-Fi from my room, but I got fine reception down in the lobby and in the buffet. Our beds were firm but not uncomfortable.
The lobby and casino are indeed smoky. Every hotel lobby I have visited in Vegas that is connected to a casino smells smoky. If this is a problem for you, it would be better to go to a hotel that has the front desk separated from the casino. The smoke did not bother us in the buffet, though, and it did not reach our room.
The bottom line is that the Boulder Station is decent lodging at an economy price (at times less than the nearby Motel 6). If you can stand the smoke in the lobby and the noise from the neighbors, it is well worth the average of $40 per night we paid including the $12.99 resort fee and taxes. The inexpensive buffet downstairs made preparing for and returning from our day out at Valley of Fire State Park convenient.
The good:
* Convenient location
* Decent buffet breakfast for $4.99 and dinner for $9.99 (with free Station Preferred Card)
* Clean, specious rooms
* Low price
The bad:
* Smoky lobby
* Noisy neighbors
* Can't access Wi-Fi from room (can in the buffet and casino, though)
