For booking hotel suites, it is often best to call the hotels and talk to someone. I love booking online (and usually do so), but I'd suggest doing a Google Maps business search for hotels in PCB, then getting on the phone.

You might not find a "penthouse" type situation at most hotels, but often the best suites will be on the highest floors.

Like the idea of renting a home, but if you are single guys and want to be scamming the chicks (er, meeting many fine young women who are also on vacation), much better odds lounging around the hotel pool and casually letting it get around that you are the guys with the suite on one of the top floors.

Per limos, call everyone and negotiate. They will try to tell you that Spring Break is prime time, but in reality... how many spring breakers rent limos or town cars?

PS I'm a cigar connoisseur who like to send some to the troops from time-to-time. If you know any groups of friends over there that would enjoy some sticks (cigars), PM me with their info.
