You need to be aware that the KTTW card won't exempt you from my magic+ problems though because it works via RIFD chip also. The KTTW at pop also doesn't have a magnetic reading strip to allow you to pull FP-. So if you are staying at pop you will essential be getting a KTTW card that is just a bandless magic band. This is actually true for all value resorts now including AoA. Not trying to squash hopes just want to make sure you are aware for what you are going to be dealing with. If your son has cognitive disabilities I suggest looking into the
DAS which may help even out the process for you guys if his difficulty is understanding waits, changes in plans, etc. I'll be crossing my fingers that your trip is smooth as butter and that you have a great time.
