No, you are not suppose to park at a monorail resort and then head to MK. There are signs at each monorail resort stating this.
They will issue you a 3 hour pass.
The parking at the monorail resorts is not meant or designed for MK parking.
I've stayed at the CR 3 times now and have sometimes had to drive around for more then 1/2 hour searching for a spot. It's very frustrating.
If you want to start your MK day at a monorail resort then park at the TTC.
