I used to be a FL resident and lover of IOA. Sadly I moved out of FL 11 years ago and haven't been ever since. We'll be at WDW for 7 days next week and have park passes only for 2. Since the weather will be cooler than anticipated, I don't think my boys will be swimming as much as I originally thought, and instead of adding another disney park day, I'm thinking of going to IOA for 1 day instead. Since I haven't been in what seems forever, my kids ages 11 and 9 have never been and my husband is not a power walker, how doable is it to get the most of it in one day? Specifically we'd be going next Monday the 7th. We won't be having the express park, I'll see if I can get a disability pass at universals as we have one for Disney for my 11 year old.
