Only been to two so far (Definitely going to Busch Gardens Tampa and Indiana Beach this year with a possibility of going to Cedar Point, Beech Bend, SF Chicago, and Mount Olympus by the end of the year.) So I might post after i have been to more parks but i would rank the parks as follows.
1. Holiday World
2. Kings Island
HW is #1 because to me it is more geared to the consumer. They listen to their customers offer nice perks (free sunscreen, soda, parking) they are CLEAN and they have the right mix between a theme park 3 Solid coasters and a water park that is tops in the business especially for a seasonal park. They are open to any and every opinion that comes across their facebook page. (i was opposed to them buying KK thinking it would take away from HW in general and believed they had no idea what they were getting into with the likes of the Kentucky fair board AND the people who actually go to the park) they responded and said thanks for my input and for being honest. Kings Island on the other hand deleted me from their page (i had to relike the page) because i mentioned SOB. I still to this day cannot write on their wall or like anything they post. What a great way to show your customers support. Sorry for rambling. just get frustrated sometimes :D
