I've had times to POP, from MCO, riding DME of 50 mins and longer at 90. That 90 was due to POP being the last of three stops...very unusual...and a ton of people at those first two stops having a ton of checked baggage with them, under the bus. When you bring checked bags with you to the bus, it holds everyone up. Those bags have to be taken out, and handed off to each guest at their particular resort. And the driver makes it take as long as he humanly can so he gets as many tips as he can. If he just put it all out there, for everyone to just grab, he wouldn't get nearly as many tips.
It took us nearly 10 mins at each of those two resorts...drove me nuts.
But, usually, POP is the first resort.
