On the days that you don't have days ticket days remaining for the major theme parks, what about checking out an offsite attraction or two? The Orlando Eye just opened in May on International Drive and its awesome!! Two other attractions, also owned by Merlin, are in the same complex: The Sea Life Aquarium and Madame Tussaud's Wax Museum. Combo tickets (admission to all 3 attractions) are only $39 pp if purchased in advance from their website. It's a great deal!!

Also in the same complex as the Eye is Skeletons: Animals Unveiled. Its a very cool museum featuring just about every skeleton you can think of (sounds gross, but trust me......its very, very well done and amazingly interesting). Discounted admission is being offered on Groupon for $24 for two people, or $42 for 4 people. I don't think the mods will allow me to post a Groupon link (they consider those referrals) but if you google "Groupon Orlando Skeletons" the offer comes right up.
Some other things you might want to consider for your "free" days......
- mini golf (there are two awesome courses right at CityWalk, and Congo River is also close by.....you can feed the alligators at the latter, which is super fun!)
- Gatorland (very "old Florida"!)
- an airboat ride (Wild Willy's or Wild Florida would be our recommendations)
- jet skiing on one of the gorgeous nearby lakes (we highly recommend Makaio Watersports.....they provide everything you need, you just meet them at the dock and you're ready to go)
- Showcase of Citrus (a monster truck ride through a real, working orange grove....they have the most delicious orange slushies at their store to enjoy after your ride.....check Groupon or Livingsocial for 1/2 price tickets)
- a beach day (Daytona and Cocoa are both only an hour away)
