I have to ask...
Why also book rooms at the del Rey in addition to your "chill spot" hotel? Are you perhaps a bit put-off by sleeping in the same beds where you had congress with ladies of the evening? I don't know how to tell you this, but any bed within 20 miles of the Hotel del Rey has seen more sex than Dr. Ruth, Ron Jeremy and Cujo, combined.
Why not follow the suggestions of others here, book your accomodations at the Sportsmen's Lodge (in the Mansion wing or top-floor penthouse only) or alternately, one of the top-shelf penthouses at Hotel la Amistad. Forget the delRey. If you want a shag shack, there are cheaper alternatives that are at least equally sleazy. Don't forget, the friendly and generous management of the Hotel del Rey charges a $10.00 per chica per visit "guest charge," and depending upon your activity level you can burn through a lot of money needlessly. You sound like a high roller and perhaps don't care, but why pay bullsh*t extra charges? So you can say you stayed at Central America's Biggest brothel? Yippie......hooray.
Book the Mansion wing or the penthouse at the Sportsmen's Lodge or a penthouse suite at the Amistad...and here's best wishes for a great trip.
Oh, and BTW... another option: C.C.I. Perhaps someone will kindly repost the link to the video onyoutube... I can't seem to see it.
