Yeah they will probably just refund your money too. I don't think this is a huge deal and frankly it's just probably for the first couple of days or maybe weeks. But we have been on this merry-go-round before with both CL and GE and all the fears the place will be so packed people will be turned away for weeks and even months on end and none of that ever happened.
Granted, difference being CL and GE are literally the biggest lands in each park and AC is pretty tiny but like everything, people will go in, do the ride if they get a BG, get a bite to eat, take a few pics and move on. Most won't stay any longer than an hour tops as there is so little to do with just a ride, restaurant and a shop. It may take a little longer to get inside but everyone will have no problem seeing it even when it opens. A month from now I'm guessing it won't be an issue at all. But probably trying to ride WEB or ordering food will most likely still be a pain.
