Hi Robert!
You are going to have a fantastic time enjoying breakfast at
Disney's Grand Floridian Resort & Spa with your friends! Morning is one of my favorite times of the day at Disney's Grand Floridian Resort & Spa because it is so beautiful in the early sunshine, so it will be the perfect backdrop for your breakfast.
While you are visiting Disney's Grand Floridian Resort & Spa for your meal, you are welcome to utilize
self-parking or valet park, as well as while you're enjoying the shopping, entertainment, and recreation at the hotel. Unfortunately, you are not able to leave your car there for the entire day if you are planning on visiting other areas of Walt Disney World Resort, including Magic Kingdom and the other theme parks.
If you would like to visit Magic Kingdom after breakfast, I recommend that you either move your car to the Transportation & Ticket Center (TTC) after breakfast and ride the
monorail to the theme park or park at the TTC before your breakfast and use the Resort Monorail to travel to Disney's Grand Floridian Resort & Spa to meet your friends. Then after breakfast, it's just a quick ride on complimentary water transportation or the Resort Monorail to continue with your magical day!
Feel free to come back to see us if you have additional questions. T-T-F-N, ta ta for now!
