Totally fine. We stayed in a comped room of some friends and it was clean and comfortable and A OK. PH is located at a great spot on the strip. Would we have chose to stay at PH if we were paying for it... no. BUT having stayed there now...based on location and access to other places I'd definitley consider it for a girls trip. The overall vibe of the place was not necessarily my thing... all sorts of frat boy-ish and newly 21-ers.
I'd go elsewhere for a romantic trip with my husband, but for a casual spot, would certainly do Planet Hollywood. This place is lacking in GOOD restaurants. The casino is nice, the mall attached is good.
