We are supposed to land at MCO at 1050 on 5/29. We are booked on ME, need to check in at OKW, and then have an ADR at CRT at 1400. Oh yeah, also need to activate/buy the APs to get into MK so we can go to the Castle. I'm not so concerned about when our luggage gets there but do care about making lunch at the castle. Do I need to consider alternate ground travel arrangements or should 3 hours be enough time using ME and Disney transportation?
