As others have indicated, schedule your table service meals together. Meet there and continue your evening together and leave the daytime free. Fastpasses are harder to schedule in this way, but not impossible either. They may want to go later than you some nights, likewise, you will probably be up earlier than they are and want to head to the parks earlier. Meeting over lunch at a quick service restaurant isn't that bad as well. These can be great experiences. They bring back the memories but also take into account who they are and how they have grown since then.
