My kids prefer US/IOA. Granted, they are 17 and 13, but we always visit there and buy Park Hoppers for WDW. Since we don't visit the parks every day, we like the fact that the PH's don't expire. We can recycle them for the next trip, if necessary. We also like to do Sea World every other year, and did Discovery Cove 2 years ago (awesome). All roads in Florida may lead to Disney, but there is so much more to do there than just Disney. Don't get me wrong, I absolutely love WDW, but $$ wise, there are alternatives. Have fun!
