Just to veer off topic for a second.
Disney opening parks early is nothing new, they have done it for years now at AK to have access to Pandora, and at DHS for access to TSLand. If you are reading this post then you're ahead of the game, you are informed and can plan accordingly.
We have said to be at the park at least 2 hours before for a very long time, the VQ is a great way to allow guests to experience the attraction while freeing up valuable time to do other things, sure you have to be flexible, but that's with everything at DIsney. They never guarantee ANYTHING, everything is subject to change and they say so in their website.
Now for those that will and have chimed in about the poor people that didn't know, it is on the guest, not on Disney. Would you spend thousands of dollars to come and not research? Especially with a huge name like Star Wars attached to it?
Can Disney communicate better? Absolutely. Have they ever done so? not really, I always tell people that come to be in the parks at least an hour before opening because you never know. Disney makes decisions based on security, demand and guest experience, in that order, they will open at different times depending the amount of people outside the gates.
Lots of people have also said that they should've called this a soft opening because the attraction is not at 100%, I agree that there should be some mention to this at the entrance of the park and attraction, but then for how long? how long should they keep the soft opening? they have been testing this attraction for almost a year and obviously have not been able to figure out a way to fix whatever needs ficing. So keep it closed although it will work about 75% of the time? That's a decision on Disney management obviously, but I as well as many here have experienced it, and it would be a shame to keep this closed when the experience is so rewarding
To sum up, still being early and informed is your best strategy, and again, if you are reading this, you know this by now. Have fun, I have spoken and MTFBWY
