Seems the way Disney is going, the next one might be:
A fee to wait in standby!
Think about it, 4 hours waiting for FoP means 4 hours not buying stuff!. They need that money, too!
Nah, they'll just start adding some drink, snack, and merchandise kiosks throughout the standby lines to entice people to buy stuff. Then they can put lockers at all of the rides for all of the crap people buy in line and charge for them instead of allowing people to bring stuff with them on rides as they do now.
Instead of charging for under 3 year olds, they could charge a stroller fee. If you bring your own, you're charged the bargain price of $25, $40 for a double. Since probably 98% of people with toddlers bring a stroller, plus a good chunk of those with older kids (and even some without kids), they would make bank.
Also paid "VIP" bus lines that guarantee you a seat on the bus and make it so no one has a seat unless they pay for the "VIP" experience.
A charge for the campfires and movies and pool parties at the resorts.
To use the waterslide at you resort will be $2 per ride, or you can get a daily wristband for $20.
An added fee for the new security checks (mandatory of course), and instead of money back for opting out of Mousekeeping, it will be $10/ night to have it for the values. $15 for mods, and $20 for deluxe.
Use of the baby centers will be $5 per visit.
If you want the standard soap, shampoo, and coffee in your room, they will be priced like it is for DVC- no more for free.
CMs will carry around a magic band scanner and charge your MB for every pic they take with your phone. Anyone who pays with cash or card for anything will be charged a $3 service fee per transaction (and no CM will provide change if you use cash).
