Gareth,
airnav.com is a great tool for info about airports and FBOs.
Also, fltplan.com is good for filing (if you intend to) and weather.
Both websites have feedback facilities which are handy.
You haven't mentioned it so I guess its not in your plans, but I'd give Opa Locka a miss. Have been there in a Citabria & a Citation and both times the service was pretty poor.
North Perry (KHWO) is a good place to stop. My husband landed there this week in his Clipped Wing Cub, which was cared for & washed - very nice
Hope you have a great trip!
