I'm also going to be leaving the M3P at MCO towards the end of the month, 7 days, we're about 130 miles away, figured I'd top it off to 100%, and we'd be in good shape when we arrived - going to confirm nothing plugged into USB, no sentry mode, etc.
We're going from there to a resort over at Universal when we get back, and I know they have charging accommodation (some for self, some for valet), that would mean we'd want to charge up after leaving to come home, a couple of Superchargers on the way, but I might just stop for 20 minutes on the way to MCO, then we can just not worry about it.
FWIW, ABRP shows arrival at MCO with 46% (then 40% arrival at Universal).
If your airport has FastPark (or a similar company) they have an entire bank of charging spots specifically for EVs that are meant for you to stay plugged into during your trip. I also enjoy looking at what EVs are plugged in there when I ride the shuttle by it.
MCO does! It's about 1.5 miles away, covered, and has EV charging, but while you can reserve parking, you can't specifically reserve an EV spot, only request it, and it's FCFS - they do indicate if a spot isn't available, you can get like a "valet service" option where they move you to an open charging spot when it becomes available, but that doesn't sound like something I'd want to do.
