Have 2 nites BLT and 2 nites BWV first week of Dec and customized both sets of MB's on Monday. FP+ all done also. Have changed my AK FP+ 3 times already and finally got exactly what I wanted. Funny my HS day it gave me "best option" exactly what we wanted. First try at Epcot couldn't get TT until 5:20 figured out how to change just one FP+ of the 3 and got 10am time more in tune with what we needed. Kinda scary/fun !
