This is a brand new and very elegant worship place which is exactly the opposite of a few other attraction/things to do in this industrial town called Kaohsiung (like visiting night market where people are grilling live shrimps on a stick till it is dead, aren't they Buddhist?).
Please refer to excellent direction from fellow TA reviewers unless you are going to this out ot town place with group tour. Founder of this Memorial Center is very wise, broad minded and welcomes everyone although theme of the place is Mahayana. This is a place for all ages and you could try some of those activities;
- 4D show is great for kids to introduce life of Budda.
- try a vegetarian meal at the very first building where you can find many shops in grandest scale. At least you will feel good although whether this is an important aspect of Buddhism.
- take a lot of pictures

Thing could improve: I wish there is some English speaking devotees on site. Again this is a general problem in Taiwan and I doubt it will improve soon.

Before we visited the Memorial, we though this is just going to be like another temple like setting where you will find Buddha and a place of warship. Instead it is a very well designed Museum park that is great for families and non-Buddhists. The place is huge and full of interesting exhibits and halls. We were very lucky to met a Austrian buddhist volunteer guide (Dale) who gave us a personal tour of the facility in English.
Public transportation is excellent, there is regular bus taking people between E-DA (another great fun place to visit for family), train stations.
For someone who loves more than just photo ops with the huge Buddha figure, you will need one full day to enjoy and explore. If you enjoy visiting Mesumes, you WILL enjoy the place.

DAY TWO
E-Da Theme Park

TIPS - make sure you speak to one of the English speaking visitor center member. Enjoy a great Vegetarian lunch. The place runs on donations, suggest donation US$10 per adult.

Directions: Take the “E-da” purple bus number 8501 from platform 5 exit 1 from Zuoying HSR station. It will bring you to the Buddha Memorial Centre (BMC) in about 40min.

BMC is HUGE (and new, opened in Dec 2011). You should spent a minimum of 5 hours if you want to really cover every bit of the centre. When you first enter the premises, you will enter a building that houses the shops and restaurants. On the 2nd level of this building, you can have buffet lunch for TWD100. There is a Starbucks, nice chocolatr bar, coffeehouse and even 7-Eleven store! Then, walk along one side of the 4 pagodas. Each pagoda has something to view/shop. Admire and learn from the murals along the long corridor. Once you reach the main pyramid-like building, head for the hall on the “birth of the Buddha” to get the tickets for the 4D movie. There is a fixed timing so it’s good to get the tickets first. Then, walk around the other halls. I would recommend that you walk the first level, then the 2nd level and lastly, the third level. The 4 stupas at the corners of the 3rd level are really good places where there are less people. Spend sometime there meditating. From the 3rd level, you can also catch a bird’s eye view of the surrounding area and of the large gold Buddha statue. The buffer vegetarian lunch was really good.

I would recommend that you set out early. When I reached around 930am, there were easily 20-30 large coach buses. There were many tourists. Ideally, you could take the 820am E-da bus and arrive at BMC by 9am. You would be ahead of the groups of tourists then.

There is no entrance fee. Everything is free including the 4D movie but it will be good to make a donation on your own. There are many donation boxes around. Just drop some donations in. Have fun!
