Hi, Anna!
You certainly know how to fill a day with magic, starting bright and early in the morning! Just make sure that the night before this busy day all the Mouseketeers in your family are all in bed early so they are ready for the big day ahead.
After your breakfast at
1900 Park Fare, you can hop on a bus at the
Grand Floridian that will take you to Typhoon Lagoon.The
bus ride is about 20 minutes, but allow extra wait time for the bus (buses run about every 20 minutes).
I always like to allow about 90 minutes for character dining, so assuming buses are running frequently, you should be to
Typhoon Lagoon right around 10:00 - 10:15 a.m. if you have an 8:00 a.m. reservation. Since you plan to go directly to the water park, make sure to have your beach bag packed and bring it along to your breakfast. Your bag should be filled with sunscreen, sunglasses, swim suits, flip flops or beach shoes, your tickets or
MagicBands, and beach towels (or you can rent towels at Typhoon Lagoon).
I hope your Supercalifragilistic breakfast is .... well... SUPER!
Cathy
