My girlfriend and I stayed at the Days Inn on the north side of the Airport. I can't remember the price, but I want to say around $60. The place was a dump, service was terrible, but the only good thing was the free shuttle to the port, which was the main reason why I chose it. I am not picky on my hotels either, I am a flight attendant and have stayed in some bad hotels, but this was the worse for me, bad neighborhood. They have some outside rooms, like an old motel, which they of course gave to us. Since it is like being pretty much in the ghetto for lack of a better term, me and my girlfriend did not feel safe at all, we went right back in and requested an inside room.
Hope this helps some,
