Hi Louisa,
What a wonderful location for a work conference! I could not think of a more magical place to work and play.
You will not have to pay the fee for the third person for the entire trip. On the day they plan to arrive, go down to the front desk and add your party members as day guests for the number of days they will be joining you. You will only be charged for those days.
I would ensure that all of your party members are connected to you and can share plans within
My Disney Experience before the trip. This will make it much simpler to plan dining reservations with them. Dining reservations book up quickly during the summer months, so I highly recommend going ahead and booking the meals you would like to share once your trip moves over to all play and no work! Your online booking window for dining reservations will open 60 days before you arrive. Check out the
online reservation system and book them as early as possible to get everything you want!
While visiting Disney World, head over to EPCOT for the
International Flower and Garden Festival. It is one of my favorite festivals that Disney World puts on because they have beautiful character topiaries throughout the park, outdoor kitchens with delicious food, and live music from some famous recording artists.
Happy Planning
Jenna
