Hi all, I am debating on-site vs. off-site - one of the big deterrents is needing a car if we are off-site. Driving in unfamiliar surroundings adds LOTS of stress to a vacation for me, especially in lots of traffic. How easy is it to drive from MCO to the WDW area, and how easy is it to navigate once there? How is parking at the parks? Any info would be appreciated - thanks.
