The Red Barn in Valrico is cute. What about McDonald's? They still have party's and are fun for the kids (About 2 hours). The parks are nice. You can buy $5 pizza's from Little Caesars. Take a pinita and let the kids run on the playground. A firehouse is fun but you have to take tables and chairs. My daughter and her friends loved this party. Pump it up (on Lumsden road) is very popular but very expensive. You could do a roller skating party or a bowling party. Maybe a craft party? Just tossing out suggestions. Hope you find something fun to do. Good luck!
