Sorry if this is a dumb question, but on our next trip to Disney in the fall we will be joined by my parents who are booked under a different reservation. I have linked DH, DD and my parents to me in MDE but my parents will never ever go in to schedule anything. Will I be a able to book the rides at 60 days for all 5 of us at one time? Especially of we are riding together? Parents don't even have smart phones so I really will be responsible for everything including any changes we may need to make. Thanks!
