The experience was decent. The scenic area was quite nice, with plenty of greenery and fresh air. The shuttle bus was very convenient, saving you from backtracking. Combined with the underwater world, it made for a fulfilling day.
There were a lot of performances, but honestly, they were all pretty much the same. You don't need to watch every single one; just pick one or two. The Water Splashing Festival was much less impressive than the Dai Ethnic Garden; the scale and atmosphere were significantly weaker. If you want to experience water splashing, I'd recommend the Dai Ethnic Garden.
Adult tickets felt a bit expensive, and the value for money was average. Hopefully, there will be discounts in the future. Overall, it's still worth a visit, just don't have too high expectations for the performances and water splashing.
