They did specifically ask about USH. But the best place to get USH information would probably be a board or site dedicated to USH.
Based on what I heard, soft openings will begin June 17th. So, if everything remains on schedule and you're persistant on checking the ride out on the days you mentioned, you should have a pretty good chance getting on USH's Mummy.
Speaking of their Mummy, just right now I'm looking at photos from their version, and I'm shocked by just how different it looks compared to USF's version.
