Hi Leah!
Thank you for visiting the Moms Panel!
I would arrive at the Magic Kingdom theme park approximately 15-30 minutes before your 9.00 a.m.
Pirates League reservation. You will see one entrance will be open for early reservations - if you report to the Cast Member at this entrance they should have a list of all the early reservations and should admit you to the park in time for your 9.00 am appointment. If you have a reservation confirmation number, bring this with you.
If the Magic Kingdom has Extra Magic Hours that morning, the park will be open at 8.00 am. Check the
calendar for the date of your visit.
I recommend allowing at least 60 minutes to travel from your room to a theme park by bus. To arrive at Magic Kingdom by 8.30-8.45, you should try and leave your room by 7.30 a.m. The buses start operating approximately one hour before theme park opening time.
Have a magical vacation!
