My biggest complaint about Walter Reed were that they did not mesh well with the Tricare appiontment system, so every appointment I made through Tricare for Walter Reed... was not in their system. I eventually had to give up and go to Bethesda (which does have better service).
And the other complaint was it’s location. The medical facility at Andrews is the easiest of the (formerly) three medical facilities in the Washington area. Bethesda’s not as easy, but Walter Reed... geez, there was no good way to get to it from anywhere outside of Washington, D.C. itself.
Understood that the administration department at Walter Reed was screwed up, but as far as treatment for our wounded warriors, treatment was excellent.
If you think access to Walter Reed was hard, Bethesda will be worst. They already have parking problems on base and the local roads are insufficient to handle the extra traffic. At least at WR one can park on the residential side streets.
I highly recommend taking Metro to Bethesda if you go there. I believe there is an internal shuttle bus but it could be only during construction.
