The Universal reps seem to tell everyone a different story. I booked an onsite hotel several months ago for May 27 - 30. I called yesterday because I had read conflicting stories about whether anyone besides HP vacation package holders would be allowed in if the park opened prior to June 18. The first agent I spoke with was totally rude. She just kept saying "The only information we have is that the park will open June 18." She was very short and when I told her some things I had read on the Universal website that had changed later that same day, she denied it and argued with me. I then asked to speak with a manager, who was very nice, and told me that if the park is open early, beginning May 28 anyone who has a HP vacation package or who booked a tour with Virgin or who booked an onsite hotel prior to March 25 would be allowed access to HP. I then asked if that access would be restricted to certain areas or if those people would be allowed to access any attraction, including all the rides, and she said whatever is up and running at that time would be available to those people. She said to keep checking their website frequently, as they are expecting more information to be coming out shortly.
