Start with conversations, not itineraries. Ask what they are afraid of (stairs, cold, unfamiliar food) before pitching destinations.
Build in dignity: private bathrooms, fewer hotel changes, seating when queuing is unavoidable. Luxury is often comfort, not marble.
Split the group when needed. Parents rest; kids hit the theme park. Reconvene for dinner stories.
Keep one shared sheet for medicines, emergency contacts, and the day’s bookings, offline. Boring detail saves emotional meltdowns.
