Mission: Space is scheduled (I think) for a soft opening in late summer and a full opening in the fall. I am going during the first week of June and am very disappointed. I guess our only hope is to be selected for guest testing, if that is still going on when we go.
Rumor is that higher ups want the drop down last day before opening to be Labor Day. That being said, there could be soft openings in August. Don't look for official openings/premiere parties until sometime after mid September
