Review for Arizona Charlie's Boulder Review For Arizona Charlie's Boulder Google User Jun 24 '16 at 4:14 3.5 stars. Pretty decent for EDC weekend. The lights are a little dim in the rooms and things aren't perfectly clean, but it's definitely better and more spacious than a cheap motel. We had a couch and two big beds, which is enough to get through EDC. About a 25 minute drive to the Las Vegas Motor Speedway. Good thing is you don't have to take the freeway to get to the speedway or the strip. View full site to comment or like
