If you land, ontime, at 5:10, you should be at Movies by 6:45. When we give you the time, it is from the gate, not touchdown. Landing to gate can add up to 15 mins or so....that's why we give times gate to resort.
So, if you land at 5:10, you should be at the gate by 5:20ish, which gets you to the DME area by 5:30-5:35. Then in line for between 1 and 20 mins, on the bus from 1-15 mins, ride to the resort is 30-45 mins, depending on which stop you are. If you take averages, that gives you about 65-70 mins from gate to resort.
I arrived on a Tuesday around 11am, and was at Music by 12:10. Everything worked out beautifully....the tram was just boarding as we walked up, quickly made it to the DME area, no lines to go to the bus, walked right onto the bus, took our seats, the bus left about 4 mins later and we were the second stop.
But it is usually around 70 mins.
If you take a car service it will take about an hour. You need to figure in the 15 min walk to baggage claim, wait for bags to come, then the 30 min ride to the resort.
But there is no way you are going to get to the resort in much less than an hour. The only time that has happened for me is when I fly with carryon bags only and use a private car service...then it's about 45 mins from gate to resort.
You shouldn't have to wait until 8pm to eat if everything goes smoothly.
