Head up to Gainsville for the college football week. Its absolutely mental there. Hope to go myself this year. Just make sure you stay overnight or at least have someone else to fly the return leg home
There are loads of places for nice day trips like key west, venice, naples. If you have more time head up to savana georgia. Only takes like 3-4 hours.
If your into seeing some nice military aircraft and a boeing manafacturing hangar then head to cecil airfield near jacksonville. I got some nice pics there.
Plan a trip up the east coast and get some pics of the kennedy space centre too.
I haven't done it myself but a few people i know planned a trip to atlanta for an overnight. Not sure what the attraction was but they enjoyed it.
I know i've mentioned a few places outside florida but its not often you get to see the states like that
