Good to know but their wait even after checking in at the resorts in both cases was more like 5 + hours. I was just wondering if that might have been a freak thing that day or if that's the norm now. We have never waited that long but in the future we'll keep luggage with us.
What time you land doesn't factor. Only when you check in at the resort does the clock start ticking. So if someone landed at 7 pm a safe guestimate is they were checking in at 8:30 or later. As the delivery window is 3-4 hours their bags were not very late being delivered, if they were late at all.
You should get your bags within 3-4 hours of checking in. Airport arrival time doesn't matter.
