Yup, yup.
Folks driving in park at the TTC and a bus or the monorail (if it's up and running) will take them to the Park's entrance. A special turnstyle is dedicated to getting people in for early morning tours and meals.
Similiarly, if you're at a WDW resort, there's an early morning chracter breakfast bus that will go around the resorts and drop people off at the various parks. They recommend being at the bus stop 45mins prior to your seating time (and letting the front desk know, just incase).
