I saw the twitter/Instagram screenshots saying, "waited three hours in blistering heat", "kids in tears, giving up." Why wouldnt you just walk to Contemporary or hop on the monorail and go to one of the resorts to relax while they fix the problem instead of standing in the heat with crying kids? Or just go to another park. Im sure Guest Relations at the other parks were well aware of the problem and would have helped in some way.
And yeah, yeah, im sure it could have been a one day trip, or the last day of a trip, or the kids reall wanted to go to MK. Either way, from the looks of the reports, they didnt fix the problem until 1 or 2 pm, so most of the day was wasted and by the time they got in, they were hot, sweaty and uncomfortable.
