Do you have to do online check in? I wasn't because I have 2 suites booked at AoA and we want to be close to each other - our reservations have travel with designated on them but that doesn't always mean that we will be put close to each other. But if I want to do FP+ and I have to do online check in then I guess if we aren't close we will have to talk to the front desk after the fact. Can you ask at the front desk where you will be if you are getting there a day before but have a room only reservation (LM) before the suite? Then maybe I won't hold up the line for online check in trying to change things when checking into the suite.
