Just thought of something else... don't the busses start running from DTD sometime around 10-11 am? So catch the bus from DTD at 10 am, get to a resort around 10:30(?), wait for a PARK bus, get on said park bus around 10:45, get to park around 11? And those are generous travel estimates. She (and her DH? Kids? - they'll LOVE this plan!) finally gets to the park HOURS after it opens.
And at the end of the day when they're HOT, tired, and just wanna get back to their hotel, they reverse the procedure. And the lines for the buses are a lot ..... a LOT.... longer than earlier in the day. It's nothing to wait 45 minutes to an hour for a bus from the parks, head to a resort, wait for a DTD bus, travel to DTD, trek to the car.
Again.... for $14?!? Hahahaha.
Next time you talk to her and she tells you of her master plan, just smile and tell her to have fun!
