Ybor City is a neat place to visit, for architecture and street shooting! If you are feeling adventurous, there are Kayak Rentals for the Hillsborough River that drop you off, and pick you up down river. Lots of gators, herons, egrets, ospreys, etc....
north of tampa, there are some rural areas...farms that could be fun to shoot.
beaches of course
pixmedic gave you some good places
i think the city itself, is neat. down by the stadium area. you could take some interesting pics of people in the city out and about, etc...
depending on your itinerary, ybor city is very cool, especially at night.
have a fun time! it's quite humid and hot here, already...pack light. lol
