I'm not sure how it works at MK but, when we went in April my DS age 5 was picked to be the Big Kahuna at Typhoon Lagoon. We were at TL about an hour before it opened(my DH has to be early for everything). We were online and one of the life guards (a super sweet girl named Megan) was talking to us and spent a lot of time talking and joking around with my son. Anyway, she asked him if he would like the very important job of being the Big Kahuna and helping her open the park for the day. We were let into the park about 15-30 minutes before everyone else, he was then given a medal that said "Typhoon Lagoon, Big Kahuna of the day!" A photographer took tons of pictures of us , especially my son. We were then given a full tour of the park, and the lifeguards all made an over head "bridge" thing that we had to walk through while they cheered, before they could proceed to their posts for the day. We then were taken to our special seating area reserved only for the Big Kahuna (it is right in front of the wave pool and is roped off, it has a table with an umbrella, chairs and a few lounge chairs too. It has a sign that says "Area reserved for the Big Kahuna". There is a box that contains the button to start the wave pool, the park doesn't open until the Big Kahuna reaches his area and pushes the button to start the wave pool. My son LOVED it! He also got a free refillable mug, (my DD also got one), 4 free towel rentals, a free large locker, the medal saying he was the Big Kahuna, a certificate and his personal favorite, 2 dozen mini donuts! The photographer followed him around for a few hours and all the life guards and staff were so sweet to him and called him the Big Kahuna everytime they saw him! He had a BLAST!
