I believe that the tentative soft opening date SAS gave is still correct. April 9 is the date they are still aiming for from what I understand. Also, in the internal FAQ sheet that Universal puts out to all their team members with answers to guest questions, one of the statements is about the availability of the WW to non-package-holding guests from May 28 until June 18. The answer is just as the guest services team members have said over the phone. However, if you read the entire document (which only team members may do) and read between the lines, it's clear what Universal is saying. They are virtually guaranteeing that anyone who bought a package from 5/28 to 6/18 will get in and experience the full attraction (rides, shops, etc.) as long as it is within the park's power to do so. They won't close for routine repairs or upgrades, have private parties, etc. that close the area to the package guests. Regular guests who did not buy the package are not entitled to that guarantee. It's still a routine soft opening for them. If they need to work on something, they'll work around the 100 or so package guests, but keep the gates shut to everyone else. My guess would be that based on the need to keep a majority of the area operating for the guests with the package, you'll be pretty safe to experience the area if you have regular park tickets at least occasionally throughout the day. It will all depend on how soon they soft open and how ready for regular crowds they are by the 28th. Also, the FAQ sheet listed June 18 as the first public day of operation as well as the Grand Opening, so I would assume what they are saying is that it will be open on that day. Any media or celebrity event they do will be after hours or very late or early in the day and will allow the area to be open for most of the park's operating hours if not all.
