Here ya go Pete
www.tablethotels.com They offer the best discounts and they don't list any junk hotels.
They will all be in South Beach but hell, if you aren't staying in the convention hotel SB is probably where ya wanna stay anyways.
Believe it or not Budget has some pretty cool cars just call the actual location in advance. You aren't gonna be driving enough to really show off a Ferrari like you'd like but you will enjoy a simple convertible Jag. Competing against the 1000 other Lambroghini's on the beach is pretty senseless anyhow. If you have any kinda luxury car and good looks to match you will still enjoy all the pussy blessings the big pimp in the sky has to bestow on you!
