Drop off allowed at WDW?

[DonnyFan]

If another party is driving us to the Magic Kingdom and Disney MGM, are they allowed to drop us off if they are not planning to spend the day in the park?
We plan to spend a day at the Magic Kingdom and another day at Disney MGM; however our driver prefers to do other activities in Orlando, so we were wondering if dropping off/picking up is allowed and where would this be done.

Thanks for any answers/suggestions/tips!
