I disagree. Almost everyone loses with DAH. Disney may keep EMH, but they will dial down the closing hours every other night to try and sell DAH.
In July, MK is traditionally opened until midnight. Disney won't be able to sell many DAH tickets if the hours are midnight to 3 AM. It's simply too late for most folks. Instead they will close MK early and then try and sell you back most of the hours you previously got with your base ticket for another $159. This is an arrogant move on the company's part and will further alienate their loyal customer base.
Ask yourself why MK hours for July are still posted at 10 PM closing every night whereas in previous years, MK was posted as closing at Midnight several months ahead of time?
For most folks, including on site and off site guests, it's a bad deal. However, I concede that for a few people, perhaps those not visiting WDW on any other day, it's an OK deal. However, that's a pretty narrow demographic. So far, the public rejects this offer. I hope that continues.
