As a Disney fan who enjoy them parks with great rides, nice and clean facility, as well as friendly and well trained staff, Yi-Da World Them Park AKA E-DA World gave our one day visit a 100% Disney like fun with only 25% of the cost. (When I add cost of admission, food, and gift shops all together)
By size, the acreage like half the size of the Disneyland Park in Ca, but because more than half the rides and attractions are indoor in multi level buildings (yea, that means no rain or sun while waiting in the line, and easy access from one attraction to another)
By attractions and rides, they have world class rides and facilities, any where from kiddie rides to space mountain like roller coaster, and guess what, they even have a "Soaring over Taiwan" ride, just like Soaring Over California in California Adventure in Disneyland Resort, which showcasing a simulation ride "flying" over beautiful Taiwan's many natural landscapes.
Becasue we are travelling with our 5 year old, we apprecate a whole building with more than a dozen kid freindly rides.
Shows - they offered Parades and Shows free. They hired performerces from eastern europe with world class productions.
One of the show was in the E-Da Theather, a very beautiful Perforamce Center and a MUST MUST see.
Food and Gift Shops - For less than half of the Disneyland prices, there are many themed dining options to chose from. Anything from Bugers and Fries, table service dining, to local street food kiosk. Gift shops are plenty, with fair prices.
Employees - are well trained and follows safty procedure very well. They are all friendly.
Tips - Stay at one of the two hotels in the area. Walk to the Mall for dinner and shopping. Allow another day to visit the 1 year old Buddha Memorial Center only 20 minutes away via US$2 shuttle ride. Very inexpensive shuttle ride to and from the High Speed Rail, City Center.
