You might make it, but there won't be any time to freshen up. You're going to have to literally run and even the slightest delay will mean that you won't make it.If our flight arrives at 5:30 am, what are the chances of making an 8:45 PPO meal in MK?
We are staying at the Grand Floridian, so we could take the monorail, but would that leave enough time to freshen up and drop our carry-ons at bell services?
Unless there's an unexpected issue, you should be fine. Of course, the only time I've ever booked something less than three hours after landing was the one time my flight was delayed by three hours!!!! My function was at the CR, I was staying at BLT, should have been a no brainer. But, I arrived just as the function was ending!!!
Barring any unforeseen circumstances, you should be fine. Land at 5:30, arrive at the GF by 7-7:30, drop your bags, freshen up, on the monorail by 8. And if you are late, ADRs get held for a bit...probably up to 30 mins.
OP didn’t say where ADR was. Some will be held more than others (crystal palace, almost certainly).With all respect to our esteemed moderator, you should have worded it "Typically ADRs get held for a bit". It is not guaranteed. Not to mention, you are not giving the OP any time from landing to getting to DME. I'd add at least 30 minutes to your timing.
You're forgetting Orlando traffic at that time of morning. Even though DME stays off I4 for the most part, side streets are still very crowded.OP didn’t say where ADR was. Some will be held more than others (crystal palace, almost certainly).
But, the timing of goofy was spot on.
Land at 5:30
Arrive at DME at 6:00
Bus departs 6:30
Arrive at GF around 7-7:30.
