Hi David,
Welcome to planDisney! It's nice to see you stopping by again with another great question.
Disney's
Disability Access Service (DAS) has been a lifesaver in the parks for my family so I am glad to hear that you are planning to use it. To answer your question, yes, that has been my experience. I also chatted with a cast member who confirmed that each guest in your party can only have two advanced DAS selections per day that everyone has valid theme park admission. I will say that having two advanced selections is wonderful and has been enough to help make our visits manageable.
When you get to the park, as soon as everyone has scanned in, go ahead and add your DAS selection for the day. So, you will have your two advanced selections plus the "rolling" selection. Once you scan in or the time window expires for that "rolling" selection, you can make another DAS selection. One of our girls takes charge of making the DAS selections while we are in the parks because she is good at remembering when we need to make one so that we save time.
As you go through the day, just keep an eye on those selections in the
My Disney Experience Mobile App. From time to time, an attraction has not cleared for a guest in our party and then we cannot make another selection for that person. If this happens, just stop by a Guest Experiences Team blue umbrella - these are located throughout the parks. Someone can help you clear it!
David, looking at your arrival date, I am excited because you will be able to visit the
EPCOT International Flower & Garden Festival. This is one of our favorite festivals. We love the topiary displays and the scavenger hunts!
Magic and memories,
Donyell
