Question About Split Stay/FP+

[erineab]

We will be statying at POFQ for 4 nights in March, followed by Wyndham Bonnet Creek for 7 nights. My parents will be staying with us at both POFQ (in their own room) and WBC. My parents are in their 70's and not up to long days in parks, so at this point they have opted not to purchase park tix this time around (room only reservation).
My sister and her husband have decided to join us for the 7 nights we will spend at WBC. We will be going to parks on several of these days as well (even once we are no longer staying on Disney property). My parents are now considering getting two day park tickets to use the following week (after we leave POFQ) when my sister and her husband will be visiting as well.
So, my question is, if they purchase their tickets now and link them on MDE, can I link them to our FP+ bookings, even though they will be using the tickets a few days after checking out of a Disney resort? Specifically, we are staying at a Disney resort from March 4-8, but they would want FP+ bookings for March 11th and 13th. I know that I was able to make FP+ bookings for all the days that I am attending parks (including the 11th and 13th), but I will also be using the tickets while I'm actually staying on property as well. I'm sorry if this question is confusing.

Just to make this question a little more complicated...if my parents add tickets to their reservation and then don't feel up to attending, can they give the tickets to my sister and her husband? I know the tickets would be on their magicbands so this may not be possible. I know they couldn't use one day and then give the tickets to someone else, but what if the tickets weren't used at all? Please don't "flame" me if this is an inappropriate question! I'm just attempting to weigh the pros and cons of purchasing the tix in advance and getting access to fp+ when there is a possibility that they may not even use them. It is difficult to predict how my father will feel on any given day as he just completed cancer treatments a short time ago and still feels the affects.
