Hello Clare and welcome to the Disney Parks Moms Panel!
We love to start our days bright and early so knowing just how early is very helpful. As a rule,
Disney Bus Transportation starts about 45 minutes prior to park opening. In my experience, they can run even earlier than that so we always plan to get to the bus stop about an hour before we hope to arrive at the park.
If you have an early morning dining reservation, your
Disney Resort Hotel may have a designated bus for this, so be sure to check with the Lobby Concierge to make sure you have plenty of time to get to the park.
You can read all about the
Walt Disney World Bus Service on this information page. Wishing you many fun mornings at the most magical place on earth, Clare.
Happy planning!
