Also, I was going to wait until the second part of our split stay to upgrade our tix. I didn't want to chance messing up anything to do with our reservation. So, we are staying at AKV for 2 nights, then moving to BLT for 5 nights. I thought that I would upgrade our tickets on our first park day after moving to BLT. But, all the FP reservations I made before then will remain intact right? We also have our son and friends with us that will have 6 day MYW tickets and they will just use them for the stay. So, its only my DH and I that will be upgrading.
