We used it this year and loved it! Here are the features we really enjoyed:
Character pictures before and after the race (Mickey and Donald)
Porta potties with handwashing stations - real running water
Bar style tables with stools so you did not have to sit all the way down after the race
Bagels, coffee, juice, miffins before the race
Bottled water to take with us to the start line
Full breakfast post race - bacon, eggs, potatoes etc. Best breakfast I ever had!
Lots of message tables available post race.
Air conditioned area to stretch and relax before heading back to the resort.
It might not be worth it to everyone but we totally enjoyed the experience.
