Keeping to my mantra of getting out of Bangkok more often I recently visited Santorini Park. On a normal day this is about 2 hours south of Bangkok on the way to Hua Hin. It's pretty hard to miss as the ferris wheel towers above the free way and will assure you of your arrival. You really can't miss it.
For Thai people this place is superb because it offers them the opportunity to do what they do best, take pictures. Thai people can not get enough photos. The developers of this park knew their audience well. MY STUDENTS ALWAYS KNOW MY FAVORITE 2 LAWS OF WRITING AND PUBLIC SPEAKING. "Audience and Purpose, Ajarn," my students just mumbled. Well they got it right at this park. Hip little shops wind around cute rides until you reach the main court yard where the big rides dominate. There are more photo opportunities here than even the Thais can exhaust in a day. It is currently at about 75% capacity, as some shops have not yet opened, but with the crowds flocking down from Bangkok and up from Hua Hin I predict great things for this ambitious cross between an outlet mall, theme park, and photo set.
My highest recommendation is for the 6D shooting game. Only 4 minutes long, but the visual quality is amazing, the seat is shaking, there is a breeze in your face as you zoom along, and best of all "YOU GET TO SHOOT ZOMBIES!" If you are courageous, I mean really fearless, you can try the sling shot--video footage follows.
