You're a wealthy tourist heading to the southern end of Taiwan for a couple days. What do you do? Well, you probably go to E-Da World.
I stayed until the park was closed, but they left the lights shining as I waited for the bus back to the train station.
If you're curious about food options, know that in addition to smaller locations throughout the theme park itself, there are plenty of restaurants in the mall area.
E-Da World may not fill your entire day, but you can certainly spend more than a couple hours here riding all the thrill rides a few times and walking through the mall. I bought an all-day pass that included a ride on the Ferris wheel and found a way to enjoy the entire day there by re-riding the coasters and other thrill rides and trying a lot of the smaller rides I might skip at a busier park. A free pass for the day is NT$899, and the park is open until 5pm (much later on weekends and certain holidays, and in the summer ). Buses from the high speed rail line and other important locations around Kaohsiung go right to the park (every 15-30 minutes from the high speed rail station, less frequently from other locations). Look for bus #8501 from HSR, or 8502, 8503, 8504, 8505, or 8506 from other locations.
