Mercy! After reading a few posts from here I seriously thought the place was downright terrible and a failure. After visiting a few days ago, I have to say, the harsh negativity here is crazy. Perhaps it's the fact it lowered my expectations by a long mile that helped. Many points here are very valid without a doubt but just exaggerated from my experience.
First of all, I really liked the slides (very thrilling) and the theming of the place, but of course there are many bugs and many things still aren't complete. The food was fantastic and the staff were very nice to us. A lot of the slides experienced downtimes (which should and will be reduced after a few months) which impacted how many slides we could ride. We rode about 7 slides when we went, with the max wait time of 225 min for the water coaster. The wavepool was really nice, and we experienced different waves. We also enjoyed the two lazy rivers, and even though the view inside the volcano was hideous, we thought it was cool to see inside the volcano. I, for one, am glad they kept the sides of the lazy rivers smooth (even though it kinda killed the theme). If it were rough, I probably would've received bruises from bumping around.
After reading so many posts about TapuTapu being a automatic failure in the first weeks is hard for me to comprehend. 3 weeks isn't enough time to iron out the many, many bugs a new service or product has to offer. It's like saying the Gringotts ride system is a failure due to the fact it kept going down in the first months. It's now one of the dependable ride systems at Universal. or it's like saying a new game is a failure a few weeks after debuting.
To sum it all up, Universal rushed this without a doubt, and that was a poor choice. It's backfiring on them and impacting many guests' experience. That shouldn't be an excuse to call VB/TT a failure for the future though. From what I saw around the park, this isn't the final product. They're adding more in, and they're still working on improving TT. We aren't waterpark people, but my family did agree that they did want to come back soon with VB "guest ready". I would give VB a 8/10 for now.
