That is a whole month, it's worrying to say the least. The dip in hotel rooms. food and souvenirs will hurt the company a lot.
I know Universal gets a lot of hate for not announcing rides years in advance but this is for sure part of the problem. Another one is banking on the wrong trilogy and not building a recognizable area. Staged opening also doesn't seem the right choice, probably done to spread development cost and the hope to keep the hype going. Jacking up the prices of tickets, blocking out most AP's and the hate for later Star Wars movies got from long time fans wouldn't help either. Add mediocre reviews for the only ride, the up-charge experiences and the negative reviews of part of the food and drinks and the broken light-sabers.
Put all that together and it seems like a huge amount of wrong choices where Disney clearly don't understand their fans, Star Wars fans and what their theme park is worth to their customers.
I'm sure aggressive cuts will be in place, hurting the brand further, to make up for lost revenue. The spin doctors will work overtime to put the blame on earthquakes, heat and whatever they can blame for outside the company. But the most worrying to me is the future of big investments. Avatar Land was expensive and only shifted the visitors around but didn't add new visitors to the mix in Orlando (judging from hotel sales I hear frequenter at the Dis). What if this is another misfire where it doesn't mater how much money you trow at the park, it doesn't matter so why do that ever again.
