Agree with all your points bar the last one. If a park announces an opening date, they should be able to commit to it opening that day. I know technical issues happen, but it is hardly the fault of the people purchasing tickets. Or are we at a point now where we have to disregard the opening date and visit once it's open. Even if you choose to wait, we still have no confirmation of an opening date - it could be months late for all we know currently.My thoughts:
1) If you are a seasonal park you need to make an effort to put contingency into your projects greater than a few months.
2) Merlin shouldn't have announced an opening day.
3) Enthusaists have seen Disney, Phantasia, Europa and others miss opening dates, stop booking expensive trips to visit for a pointless opening day credit ride unless you build in contingency.
Appreciate others may disagree.
