I have a Feb 2018 trip planned for me, hubby, 9 year old son and my sister. My sister is on the split-stay room reservations that we have for AKL and Poly. We plan to tack on one night at the beginning at AOA (didn't have enough points for this additional night even with banking/borrowing/OTU points). I know that I cannot purchase the current 7-day ticket for the price of 5 for my sister since she doesn't live with us so she will have to purchase her own. My question is...will I be able to link her WDW ticket (she might buy a 4 night or a 5 night, not sure yet) with my MDE so that I can book all of our fastpasses for the same rides? Also - will she have to buy her own Memory Maker or will I be able to get the pictures on my account that we take with her?
