There hasn't been a soft opening, only a limited press walkthrough. The rides aren't operating yet. Here's an article:

Edited to add:
I just read that they had a preview for 300 guests the next day and ran the rides. You'd think they'd have made sure the people giving them the free advertising in the press got to ride the day before...
I know that of my 4 friends who work at Universal, though not in the HP area, only 1 has been through training. I wonder how many of the people who got to go are actually employees being trained to answer questions about it.
