You can certainly drive to the front and have bell services unload and store your luggage upon arrival and then park. If you prefer to determine if your room is ready, you can park and leave your luggage in the car. That allows you the option of schlepping your own luggage to your room rather than having bell services handle it. Totally your decision.
Upon arrival at the entrance, you will be asked for your name to verify your reservation and if you choose to park, simply ask for direction from the guard at the gate. If you choose to go the bell services route, pull to the Porte Cochere and allow the attendants to unload and store your belongings. If YC is on top of the ball, you should be greeted at the front door by someone from CL to take you up and check you in. If not, go to the front desk and you will be directed from there.
Hopefully you will receive your "room ready" message prior to your arrival.
One final note, you will be charged for parking--I don't think CL now includes waiver of parking fees, but I could be wrong on that one. We haven't driven to Disney although we had a rental car a few times and that was pre-parking fees.
