paris only received two stars for a very simple reason. a very bad experience for me with the valet service....
the casino itself is sub par - given the effiel tower is a nice sight to see - if you're looking for a euro ambience i'd recommend the venetian or ceasars palace over paris. the staff (during the day) was more suiting for the Mandarin Oriental as 75% of them were Asian so i didn't feel as if i were in Paris - the decor and sky painting on the ceilings lacked a wow factor. not as mesmorizing as ceasers palace or the fresh feel of the venetian.
as far as the valet service goes - the drop off was as easy as any other hotel there. but as paris was a quick stop before the airport for my friend and i... when it came time to get our car it took 18 minutes of standing there waiting and watching everyone come and go but us. when i asked the valet attendant what the hold up was he said "it's coming. just wait" unacceptable by my standards. would have been much faster to park my own car.
