We booked into a slip at the Tampa Convention Center. The docks here are nice floating concrete docks and you are just steps away from the Trolley and many restaurants. The issue here is a lack of security. We've been here two nights and had people board our boat around 2:00 AM both nights. Night one was a group of 4 young men, who we think were trying to steal items from the center console beside us and jumped on our swim platform. Last night, a couple decided that it would be fun to have the girl lie on the bow of our boat for a photo shoot. (our main bedroom is in the bow).
There is no security gate, not even a sign saying private and the dock is shared with paddle boats, rental boats, booze cruise, and tiki boats. The dockmaster is said that the Convention Center is in charge of security, when we called Security last night, they said they would "send someone to check on the docks." We were up for over an hour calming back down, and we never saw them.
So, nice facilities, but poor security. There are other marinas in the area, not quite as convenient, but I'd give them some consideration.
