1) Cedar Point - Pros: amazing atmosphere, so many incredible coasters, including my number one (Mav), ten (MF), and eleven (TTD), best flat ride collection of any park I've been to (Skyhawk, MaxAir, Power Tower), morning ERT, location on peninsula, various places to stay on the peninsula make the experience much better
Cons: almost too big, distance between rides limits the time spent actually riding, normally very busy
2) Lake Compounce - Pros: fantastic atmosphere, possibly the most fun coaster I've ever been on (Boulder Dash), the park is normally dead so I can always get a very high ride count whenever I visit, great flat ride collection, beautiful landscaping and locations with lake and mountainside, solid coaster collection (BD, Phobia, and Wildcat), all rides are close together
3) Hersheypark - Pros: phenomenal collection of coasters with great top two (Skyrush and Storm Runner), Hershey's Chocolate World, beautiful landscaping especially by Skyrush, Great Bear, and Storm Runner
Cons: hardly any flat rides, annoying weather policy
4) Knoebels - Pros: very friendly park, ability to pay per ride, great coaster collection (Phoenix, Impulse, Twister), great flat ride collection, park museum
Cons: pricey all day pass
5) Six Flags New England - Pros: Best duo on Earth currently, my number three (STR) and five (WC), good unique flat rides (Buzz Saw, NESS), good coaster lineup
Cons: Assigned seating on some rides, some missing pieces in coaster lineup (no launch coaster and no good wooden coaster), too many bad/painful coasters (Mind Eraser, Flashback, Goliath)
6) Six Flags Great Adventure - Pros: great coaster lineup (Toro, Nitro, Ka)
Cons: many coasters in the park are overrated (Toro, Bizarro, Nitro, Joker, Green Lantern), horrendous park set up, similar problem to Cedar Point (extremely far from Ka to Toro to Nitro), not many great flat rides
7) Canobie Lake Park - Pros: good atmosphere, many flat rides
Cons: weak coaster collection
8) Sea World San Antonio (both Steel Eel and Great White were closed) - Sea life is fun to watch, decent coasters, Wave Breaker will help coaster lineup a ton
Cons: Ride closures (not sure if it is a normal problem, but hindered my opinion of the park), very few rides (no flat rides)
