Yeah, their website was a bit lacking. At least they could give you some hours and schedule of the shows. I would suggest getting there before lunch so you can see all the shows. I missed out on several of the shows since we arrived after lunch. We stayed until the place closed and it wasn't so easy finding a taxi to take us home. That easily could have changed in the past 4-5 years since Bangkok has such a high rate of development.
How was Dream World? Is it fun for an adult? Did everything look safe to you?
