We love the weekend events and it just keeps going, something fun is keeps us home most every weekend. I really liked the River O'Green Fest on Saint Patrick's Day. Not sure about the money it cost to turn the Hillsborough River bright green, but the party was good. The best part was the food and live music entertainment. Also set up was a variety of children's activities, a family event.
Try the Tampa Downtown Market on Friday Afternoon. I like the vibe downtown on the weekends too. Saturday and Sunday is so different than the weekdays. Here you get good food at cheap prices from local farmers and organic producers. (200 & 300 block of Twiggs Street)
One great thing to checkout is the Great Urban Race, a wild urban adventure. Teams solve clues around the area using and overcoming mental and physical challenges while discovering the City of Tampa in a fresh way!
Make sure to see the video about the Florida Aquarium. The Aquarium is right next to the Convention Center and it is closed to the public during the convention. The delegates are having ten parties there during the convention. It looks like a really nice place to have a party.
