It's a common and bad trend Universal opening rides, parks and hotels too early.
Surly there are unforeseen delays every single time and every single time it's not ready. In the end they fix it but it is bad show and unprofessional. If a ride, park or hotel was in "technical rehearsal" than no one would complain. If the big opening is a month or two later, no one will complain. But if you say the ride is open, book your vacation, and it's close half of the time than it's ignoring the customer experience.
This clearly has to change Universal and if you want to have help with that you can contact me for my usual fee.
