In my opinion, the waterpark has needed some TLC for ages and has ALOT more potential than what KI has given it. The additions have been nice but nothing there really makes you say "wow.... thats an attraction I would wait for hours with 200 other sweaty people".
I worked at Admissions a lot at Soak City last summer and came to kind of enjoy working in the area. I think over half of my supervisory shifts were at Soak City lol last summer. It also really made me evaluate some of its strengths and weaknesses. Its strengths ironically is also its weakness, open areas with few trees. The concrete hurts like heck if you are not in sandals, which I think that KI needs to invest in that less heat concrete that Holiday World and Kentucky Kingdom have in spots. People who want to get a tan have PLENTY of space to lay a towel out, especially underneath the power lines. The front gate needs some slight improvements (the sales booth/guest services is from personal experience incredibly cramped.) with like one more turnstile to really make traffic flow in and out at peak. Security also needs to be pushed back slightly to prevent backlogs. The one thing that stands out is there needs to be some of the same amenities at the main park with at least one location in Soak City. Wheelchair Rental or Stroller Rental does NOT exist in Soak City which can cause significant guest inconvenience in having to get one from the main park. The merchandise locations are suprisingly okay, there a couple of stores. First Aid and Security have their own offices at Soak City, which is good, but the other things do not exist. Other than Island Smokehouse, the food options are significantly lacking in quality. Fast Lane only truly skips the line for one slide, Tropical Plunge, and only skips the line to get mats for the others. The wave pools are great capacity wise but also do not have many things that make it anything other than a Public Pool with Waves. The slides are getting very old at this point and a major slide complex has only been added once since 2004, Tropical Plunge.
They had some good ideas, Island Nights was a great idea for Soak City that was VERY poorly advertised. Keeping the water park open till 10-11 with live music, silent disco, etc was a good idea but was not implemented to its best potential. They should have kept at least one wave pool open during that time.
Soak City has a lot of land to expand on, even accounting for the power lines. And has a lot of potential that needs to be met.
Hurricane Bay and Splashin' Safari are LEAGUES ABOVE Soak City in any capacity. And out of those two, I actually prefer overall Hurricane Bay to Splashin' Safari despite Splashin' Safari having my two favorite water attractions, Wildebeest and Mammoth. The atmosphere is very tropical, the Big Kahuna is the best wave pool I have been in so far, and the attractions have a bit more higher baseline of quality and are also pretty unique. Deep Water Dive alone is worth it for me to visit Hurricane Bay. Kentucky Kingdom did great by signficantly investing in their waterpark. Splashin' Safari made some hopping investments in the late 90s - late 2000s but was neglected a bit after Mammoth in 2012 until this year's Cheetah Chase, which looks to be an amazing addition. Hurricane Bay has seen a few additions but they started off so strong with 2014's additions they could afford to float for a bit.
One area that HW and KK have us beat is their water parks, and they have theirs included in admission.
