Normally to add guests to a
DVC reservation online, you would go to the DVC Member site, sign in, then under MY DVC, click on "My Dashboard," and on next page click on the particular reservation and then click "View or Modify Details" and then next page choose "Modify" for "Guest Information." That will take you to the page where you can add persons to the room. What I do not know is whether reservations for the new resort studios at VGF are actually being shown yet in your online account. If not you could call and make the addition. Note, you do not need to add any guests until it becomes necessary to do so, such as you need to buy tickets for those guests so you can make park reservations and attach those tickets to the guests in the room or want to put them in restaurant reservations
