Went on Saturday (15th) for the first time, and had a really good day! Highlights included The Volcano and Millennium (my first coaster with vertical loops!!).
Two other notable things happened that were either funny or unexpected:
1. When we went on Mystical Dragon Mountain, my boat stopped just after leaving the launch platform, and the poor operator had to actually crawl inside and give me a push!
2. When we went on the Rhombus Rocket, the restraints were locked and we were waiting to go, when an alarm sounded an announcement told staff to report somewhere and that there was a "code blue". the staff on the Rhombus Rocket started running around like headless chickens, then unlocked the restraints and shouted at us to get out of the train. Some people went down the exit while some people (including us) waited on the platform. 10 or so minutes later we heard that it was a practice, and were able to get back on and enjoy the ride (which i did).
Great day though, and Millennium was awesome!
Also, the Pyramid's theming is, in my view, outstanding for a UK park, and the projection mapping on the mountain was amazing!
