Is there a day mid-trip that you can leave free of FPs until you do the update? That will also give you the time you need to search different Guest Relations to attempt to upgrade at a, hopefully, lower cost.
We could, but I'm sort of evaluating the risks a late-arriving plane, jetlagged cranky kids, and the possibility of not being able to get our FP choices later in the week and coming down on the side of keeping the FP+ for later in the week. Here is our plan for the week. Logically, I think it would make the most sense to drop the FP for either day 8 or 9 at HS.
(1) Arrival day/no advance FP+/HS studios afternoon/evening -- hoping to be able to pick up a couple of FP+ on the day of, maybe GMR and Star Tours
(2) MK -- FP+ for PP, Enchanted tales with Belle, 7DMT
(3) AK -- FP+ EE, Kali, Safari
(4) Epcot -- FP+ for TT, Mission Space, Spaceship Earth
(5) Blizzard Beach/mini-golf (need to add the "Plus" option to do this)
(6) MK -- FP+ for BTMRR, 7DMT, Space
(7) Epcot -- FP+ for FEA, Character Spot, Seas with Nemo
(8) Typhoon Lagoon morning/HS studios evening -- FP+ for TOT (4:30-5:30), Toy Story (5:30-6:30), Star Tours (7:30-8:30), with dinner at Sci-Fi between Toy story and Star Tours and Star Wars fireworks after Star Tours
(9) HS morning before getting DME back to airport at 3:30 -- FP+ for RnRC, TOT, Star Tours at 10, 11, 12
