I dont really see what the fuss is about with all this. If you want to use it, pay for it. If you don't then just vacation as usual.
For what its worth, the Cedar Fair parks tried this out last year and it was really popular.
But the problem is money.
King's Island is in our area. Let's take a Friday as our example: Online you can buy a ticket for $35.00. You can add $30.00 for a "Fast Lane" ticket. That still makes it $65.00. And you can enjoy the entire park in one day, especially if you don't have to wait in any lines. And you can drive there, tour, and drive back to my house in one day.
My dh & I have 3 kids. That makes a day at King's Island for the five of us $325.00. I can justify that. If we go to the movies (& let kids get popcorn) & dinner at a nice(ish) place it would cost us $150.00 (we rarely do this, but from time to time) and so to have an entire day of fun (with a packed lunch, CS dinner and a few snacks) it would cost $400.00. Once a year, I can do that. Plus, I can get a deal and get it cheaper. Or I can go midweek and get it WAY cheaper.
But if you are really saying that this is going to cost over & above the daily WDW price? Let's just say comparing park to park you buy a non-hopping ticket to MK: It's $90.53. There are no "bring a Pepsi can and get a deal" deals here. Kids are adults at 9. That makes my price for my family $446.65. If a comparable pass to skip the lines is $49.99 (Universals Islands of Adventure Friday Express Pass Price) then my total day cost for one day at MK to enjoy it the way I am currently enjoying it costs $696.60.
Now. I just want to point out that you can take a 7 day cruise, a really fun, food included, 7 day cruise for $369.99 per person.
So I think my problem with WDW doing it is it's already too expensive. I already have to decide if I really can handle my WDW addiction. I'm constantly on the line. But Disney is worth it to me because I've never been treated to such delightful customer service and wonderful entertainment. Though cruises come very close.
So if they make it a worse experience for me. Or a more expensive experience for me. Then I'm going to take my same dollars and take a cruise. Or go to Williamsburg. Or NYC. Or all the infinite places I could go and enjoy.
And Disney SURELY knows that's true. Surely.
