Hello Mariana, and welcome to planDisney!
I think you are asking about making
Disney Park Pass reservations to go to
Disney's Hollywood Studios with your family. At this time, theme park capacity is limited and attendance is being managed with the Disney Park Pass reservation system. All Guests will need a reservation as well as valid
admission for theme park entry.
Check the
Disney Park Pass availability calendar to make sure reservations for your selected theme park are available on the date you would like to visit. The calendar shows availability for 3 different categories of Guests: those with reservations at a
Disney Resort Hotel or other select hotels; Annual Passholders (without a hotel reservation), and theme park ticket holders (without a hotel reservation). Reservations are limited and availability can change, so I recommend reserving your Disney Park Pass as soon as possible.
Because you have a reservation at
Four Seasons Resort Orlando at Walt Disney World Resort, choose "Disney Resort Guests" when viewing the availability calendar -- this resort is considered a "select hotel" and is included in that category. Be sure your
hotel reservation is linked to your My Disney Experience account prior to making Disney Park Pass reservations. If not everyone in your party has hotel reservations, you'll need to make Disney Park Pass reservations separately. As long as everyone in your party has both admission and a Disney Park Pass reservation, you'll be able to enter Disney's Hollywood Studios together -- it is not necessary for everyone to be on the same Disney Park Pass reservation.
I hope that helps! If I misunderstood your situation or if you have any additional questions, please feel free to visit planDisney again anytime. We are always happy to help. Enjoy your visit!
