There is no need to worry! Walt Disney World makes these early reservations knowing that many guests will not have their own transportation (such as rental cars, etc..), so they will make sure that you get there on time. There is your standard bus transportation, which of course always starts an hour before park openings, but if you ask at the front desk of your resort when checking in about your early reservation and what time do the buses depart for these...you will more than likely receive another time guideline for their early breakfast reservations. They are very good at accommodating their guests (because everyone is special in WDW) whether it is early in the morning or late at night....no one is left behind either in this "Most Magical Place On Earth." Have a great breakfast.
