If I were going to add a new attraction it would be a Mack twist and splash.
http://www.mack-rides.com/en/products/spin-rides/twist-n-splash/sr-ts-info/sr-ts-info.html It’s unique to other waterpark attractions and it’s a capacity monster.
As for operational improvements:
FOOD
• I would attempt lease out the Papaya Pete’s building (west side of wave pool); preferably to Panda Express.
• Relocate the pizza ovens to Captain Cook’s (near the kiddie pools).
• Increase the availability of food discounts to season pass holders.
• Install high speed credit card machines at ALL food locations (including mobile carts).
• Replace the pre-cooked funnel cakes with pre-packed Cinnabon.
RETAIL
• Raise the price of lockers to $10 but offer a 50% discount for season pass holders.
• Sell vouchers for inner-tubes at the ticket booths.
• Have Snoopy (dressed in a tropical shirt) pose for photos in the park.
• Close George’s Rafts.
• Relocate the haystack dryer from WOF to central village.
CABANAS
• Find a way to make reservations available online.
• Provide free wi-fi to cabana guests.
• Give free unlimited soft drinks to anyone with a cabana wristband.
ATMOSHPERE
• Bring back the classic rock/greatest hits music.
• Build family changing rooms.
• Build a designated smoking section northwest of Trader Nick’s. There are currently no smoking areas at the front of the park. At closing time smokers have to go back into the park to light up while they wait for their party to change.
