Hi Sarah,
Welcome back to the Disney Parks Moms Panel! Thank you for returning here with your questions. I am so glad that you will be able to try out the new
Bon Voyage Breakfast at Trattoria al Forno on
Disney's BoardWalk. This looks like such a fun way to start the day, dining with princes and princesses. I am also pleased to hear that you are staying at
Disney's Art of Animation Resort. This resort is full of whimsical and amazing tributes to animation.
Since there is not direct transportation from your resort to Disney's BoardWalk, I suggest that you start by taking a bus from your resort to Disney's Hollywood Studios. From there, you can either walk or take a boat to Disney's BoardWalk. For this leg of the journey, both the boat and the walk would likely take about 20 - 30 minutes, and the walk follows the route that the boat does along the water.
If you prefer a direct option, you could ask a cast member in the lobby of your hotel to call a taxi for you. This will of course have taxi fare associated; however, it should not be too expensive and would likely be a quicker option if you are looking for one.
I hope that these thoughts are helpful for you Sarah! Please do let us know if you have any further questions.
