What we do for the Dolphin....TAXI..... better than a bus for very early breakfasts. It's what we do and will do for Easter 2010.
Taxi's sit right outside the Dolphin door, yes they are good and prompt... take a taxi at 7:30 AM to the Contemporary,CR, and ask to be dropped off in the CR parking lot entrance, then pay (about $15 worth every penny). You will be at the CR parking lot by 7:50 AM.
(Cars can not go to the front of MK, only WDW buses, cars must go to the large parking lot across from MK and the lake)
Then walk on the sidewalk from the CR parking lot to the MK entrance, the monorail will be just about above you. The walk takes about 5 minutes.
So you will be at the MK entrance by 8 AM.
Go to the CM on the left (usually is there) and tell them your ADR # and CP and they will let you in (once your park tickets have been swiped).
Take a few pictures of an almost empty MK park as you stroll down Main Street to your 8:15 AM CP breakfast.
ENJOY !
