Great location in The District and connected to The Green Valley Resort and Spa. This REI is very clean and organized so you can easily find everything you need. It is smaller than other REIs I have visited as it is only one level, but it has the basics you would need anyway.
The workers are very helpful and friendly! I felt very welcome walking in and shopping here.
The parking is ample as it is located in a private lot with plenty of free parking, and if there is a need for more, you can easily park in the structures for the casino / hotel.
