Hey, howdy, hey, Kristy!
This sounds like a lovely morning plan, and I’m glad you’re thinking about timing ahead of time, as that can make all the difference.
With a 7:45am
‘Ohana breakfast, I usually recommend planning on being there for about 60 to 75 minutes. Even when things move smoothly,
character meals take a little time since you’re seated, served, and the characters rotate through. That would put you finishing up somewhere around 8:45–9:00am.
From
Disney's Polynesian Village Resort, you’ll then need to get over to
Magic Kingdom for
Bibbidi Bobbidi Boutique. The easiest option is the monorail, and I would give yourself 20–30 minutes for that, including walking to the station and waiting for the next train. Even though the ride itself is quick, little delays add up in the morning. You can also take a boat from the Polynesian, but this route may take a little bit longer, as the boat size varies, and you may have a stop before making it to the Magic Kingdom.
I always suggest arriving at Bibbidi Bobbidi Boutique 10–15 minutes early for your appointment. When you put all of that together, the earliest appointment time I’d comfortably book is 9:45 or 10:00 am. That gives you breathing room, keeps the morning relaxed, and avoids rushing little ones who are probably already excited. Also, remember that you'll need park admission to the Magic Kingdom to have access to Bibbidi Bobbidi Boutique.
If you snag something a little later, even better. A calm start makes the whole day feel more magical.
I hope your little one has the most magical experience!
Toodles,
Korliss
