I can assure you, I've talked to plenty if guys whos airlines put them up downtown and they'd rather stay in Rosemont as its closer to the airport. There's a couple of FLL lines where you're showtime is something like 6 am with traffic from downtown, I'd guess you'd need a 5 am bus. Cmon man, do you really want to get up that early? We have too many long van rides as it is. There's nothing wrong with Rosemont, it's close to the airport, plenty of places to get something to eat and the hotel is really nice.
