My parents are considering joining us for our trip this summer. If they do, I would be booking an additional room-only for them, since they don't like going to the parks. We've never used fast pass+ so I've been stressing and anxiously reading up on how it all works in anticipation of my 60-day mark. I just read on a thread about people using extra MBs to get 3 additional same day FPs. Is that allowed by Disney? If so, does that mean my two older kids could select SDFPs for 3 additional rides to go on by themselves using my parents MBs, even though they're not linked to tickets?
