Hi, Jennifer!
What a smart idea: getting your Princess decked out at the Bibbity Bobbity Boutique first thing in the morning will ensure that she'll be set for a day of royal treatment!
From the Cabins, you'll certainly want to allow at least an hour to get to BBB, either the one in Downtown Disney or the one at the Magic Kingdom. This will provide ample time for you to negotiate the
internal bus system in Fort Wilderness and the property-wide system throughout the Resort.
If you're heading to BBB in Downtown Disney from the Cabins, your best bet is to take one of the internal buses that is dedicated to the Downtown Disney route.
If you are going to the Magic Kingdom, you can take a water launch from Fort Wilderness directly to the Park. The launch stop is beside the Trail's End buffet i the campground.
Alternately, you can take a bus from the Cabins to the Transportation and Ticket Center. From there, you can choose to ride either the Monorail or the ferry over to the Magic Kingdom.
Have a super-glittery time, and enjoy!!
See you later, celebrator!
