V,
The Diria is indeed a great hotel....but as you mentioned, definitely NOT chica friendly. However, your situation is somewhat different, as you would be bringing the chica with you as a registered guest. I don't think you would have a problem with attitude, etc., from hotel employees as long as you and the chica are discreet and the chica is presentable in dress and mannerism; by this I mean........she shouldn't look like she just stepped out of the DEL REY.

I'm sure you get my drift.
The way the Diria controls "by-the-hour chicas" from coming in, is upon registration at the hotel, every registered guest has a plastic, colored bracelet snapped onto their wrist. You wear this bracelet during the entire stay at the hotel. This way, the hotel personnell know....who belongs and who does not.
