Ok...so I asked the CM who answered about what we would do if we had Park Hoppers and we booked FP+ for the morning say in MK but we wanted to go to Epcot that night, would we be able to use the regular FP system. He said he didn't know so he transferred me to one of the Internet Supervisor people (I guess one of the people who are in charge of answering everyones MB and FP+ questions). Here's what she said (after I apologized because I'm sure she got these questions like 23094820384 time a day lol she said it was no problem because they need these questions and feedback and that's what the test is for):
Upon arrival at our hotel, we will be given a regular KTTW card in case of any problems with the Magic Band. We would go to the park that we booked our FP+ for, use them and say then we headed to like Epcot. We would be able to use the regular FP system but would have to use the KTTW card that was given to us at arrival. If for some reason our Magic Bands don't work, we have the KTTW card and if the bands still don't work, they'll give us the generic grey ones. She asked me if I had any other questions, I said no. She took down my name so she can put my questions into their records so they know what to improve on and I asked if I could give a recommendation lol. She said sure so I said that they really need to up the amount of FP+ you get per day because for people who go often, we kind of have it down to a science and with only 3, it kind of puts a kink in everyone's chain lol. She said she understood and that's another thing they are testing too. So who knows lol. I hope this helps everyone who is doing the testing though! I'm sorry for posting it on here, I'm kind of scared of all the other FP+ boards lol.
