if you have to stay in downtown jacksonville this is the place to stay
I've had to come to downtown jacksonville for the last 3 years to go to a convention, I assume that's the only reason anyone would stay in downtown Jacksonville? Downtown Detroit makes Jacksonville look good- I'll never be back.
The Hyatt is THE place to stay, ask for a room with a river view.
The mexican restaurant at the "landing" next door is excellent, good food, service, drinks
