Hi Marlene!
Welcome to the Disney Parks Moms Panel.
There is something very relaxing about starting your day with the lovely boat ride from
Disney's Fort Wilderness Resort to Magic Kingdom Park. The actual trip itself only takes around 20 minutes so I would say that you definitely have enough time if you are able to board the first boat. I would ensure you are at the boat dock by no later than 8.15am. You will then have enough time to clear the security bag check, scan your ticket or MagicBand at the entrance points and walk along Main Street, U.S.A. to the
Harmony Barber Shop for your son's magical hair cut!
If you are very concerned about arriving on time you might like to consider using the
Disney Minnie Van Service. These distinctive vans are driven by knowledgeable and friendly Disney Cast Members and can seat up to 6 guests, and provide two child seats if needed. You can order your Minnie Van by using the Lyft app on your smartphone, where you will also see the cost of using this service and make your payment. You can also order regular Lyft vehicles on the same app, but please know that the only cars permitted to drive to the entrance of
Magic Kingdom Park are the Disney Minnie Vans. All other vehicles, including all taxis, must drop guests at the Transportation and Ticket Center. From there you will have to board the ferryboat or the monorail to take you to the entrance of the park, thus adding more travelling time.
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical vacation to Walt Disney World Resort.
