What are some inexpensive things for my husband and I do during his 2 week leave in Orlando?

My husband is coming back from Iraq near the end of June for 2 weeks. My problem is that during that time it is "peak" season and being on a budget I need some ideas of things for us to do. Things that are romantic and fun that won't break the bank. I'm aware of the free tickets to sea world and busch gardens but is there anything else out there?
