We stayed here back in February 2015 for the Color Run so we could be closer to the starting line and not having to drive all the way from Henderson to downtown Las Vegas.
The reason why there are three stars on this review is for when we got back from the Color Run. All of the elevators took forever to come down into the lobby, so we had to use the employee elevator to get back up to our room. Secondly, it also took forever to get the shower warmed up (after getting powdered up with lots of color, you ought to have a shower :P).
Otherwise, the D is walking distance to most restaurants and Fremont Street. It didn't take long for us to arrive at the Color Run's starting line too.
