Hi Anneka and welcome to the Disney Parks Moms Panel.
Best Friends Breakfast featuring Lilo & Stitch at
'Ohana is my sons absolute favourite Character Meal at the Walt Disney World Resort.
Breakfast is served from 7:30 AM to 12:00 PM and to be perfectly honest, no matter what time you decide to make your reservation for, you're sure to have a great time.
Personally, my family prefer to make our Advance Dining Reservations at this particular dining location for 7:30 AM. That way, we can enjoy our breakfast before jumping on a monorail to the Magic Kingdom Park in time for or just after park opening (on days when the park opens at 9:00 AM).
You will find that you have no problems at all in being up bright and early for the first few days of your visit at least due to the 5 hour time difference. I know that my family are usually up, showered, dressed and ready to go by no later than 5:00 AM for the first few days - the time difference definitely takes a bit of adjusting to.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
