L.M.
Lake Eola is in downtown Orlando. You can go walk around the lake, have lunch etc. I also 2nd going to park avenue, but if you have kids they might get bored. The Orlando Science center is really cool. Dave & Busters is on I drive ,that's fun, especially if you have kids. Downtown Disney has a brand new bowling alley that is supposedly really cool (haven't been there but I've heard good things!)
