Agree that RC Pentagon City is the pits, service is poor, restaurant is poor, I can't even get return calls from accounting on billing mistakes charged to my credit card six months after thefact.

Disagree on RC Marina del Rey, but my experience was with a suite and not a standard room (which I have heard is small, tired). Suite was nice, would have liked a larger balcony to look out over the marina. I suppose that compared to some RC properties it may not be great but (a) it's a darn site better than Pentagon City and (b) I compare it to my other LAX overnight options...
