Plan a comfortable, accessible trip for an older traveler

Help me plan a comfortable trip for an older traveler.

**Traveler(s):** [AGE(S), and whether I'm planning for myself or a parent/relative]
**Destination and length:** [WHERE and HOW LONG]
**Mobility and energy:** [e.g. "walks 20 minutes then needs a rest", "uses a cane", "uses a wheelchair"]
**Health considerations:** [conditions, medications, dietary needs - only what's relevant]
**What they most want to do or see:** [LIST]
**How we're getting there:** [flight / train / car / cruise]

Give me:
1. A daily pace with one main outing, a midday rest, and early evenings. Limit walking and stairs.
2. Questions to ask hotels and attractions before booking: step-free access, elevators, grab bars, distance from parking or transit, seating available, and accessible restrooms.
3. How to request airport or train assistance (wheelchair service, priority boarding) and when to request it.
4. A health plan: carry medications in hand luggage with original labels and a written list, enough extra for delays, how to handle time-zone changes for medication timing (confirm with a doctor or pharmacist), and travel insurance that covers pre-existing conditions.
5. A one-page emergency card: contacts, conditions, medications, allergies, doctor's number.

Recommend a check-in with their doctor before the trip if they have heart or lung conditions, recent surgery, or a long flight planned. If they show chest pain, sudden confusion, or trouble breathing during the trip, call local emergency services right away.
