I have a dilemma about this as well --
For starters, our plane lands around 10AM, but we cannot check in to AKL until 3PM. MIL is staying off property at a time share, and she cannot check in until 4PM. She is renting a car (we are not).
SIL will already have been there for a few days, so our plans were to collect our luggage, grab MILs rental and head to SILs to kill some time before check in.
Now, with Magical Express, since we're the only ones staying on property -- do you think they will take our luggage to AKL without us so we can run errands with MIL... (I feel like it would be safer to just lug it around with us...) or, if we take the shuttle, will we have to sit around the lobby for 5 hours??

Has anyone ever been able to check in several hours early?
