An air‑conditioned, wheelchair‑friendly museum that provides a concise, seated introduction to Angkor’s history — a gentle activity instead of long temple walking.
Private car + English guide to reach Angkor Wat for sunrise with minimal walking; the guide will plan short, level walks and provide shaded/seated breaks for your father and pregnant wife.
Book a 60–75 minute gentle neck/shoulder or foot massage for your wife (confirm pregnancy‑safe); avoid deep pressure. This is optional and relaxing after an early start.
Taxi to the pier (~20–30 minutes) then speedboat (~45–60 minutes). Onederz usually coordinates pier pickups; request assistance for boarding for elderly travellers.
A gentle glass‑bottom boat trip to view marine life with minimal physical strain; operators will assist boarding. Good for photos without strenuous swimming.
Short night boat to see bioluminescence — visibility varies with moon phase and sea conditions; book a small private boat with lifejackets and assistance for boarding.
Early boat to Sihanoukville so you have time for the domestic flight; request hotel pickup to pier and assistance with boarding and luggage for your father.
Pre‑book accessible seating and inform the restaurant of dietary needs (vegetarian/low‑spice). Seated performance is calm and appropriate for older guests.
Parents can have a 60–90 minute gentle in‑hotel treatment and/or a private car that drives between Angkor viewpoints with short, optional flat walks (driver waits).
Pre‑book a private low‑step car/van to collect parents at 03:00 for international check‑in; request porter assistance for luggage and airport meet‑and‑assist if needed.
Estimated lunches and dinners across the trip (breakfasts mostly included with hotels). Based on mid‑range pricing used in the day plan (mix of hotel restaurants and local cafés).
1) This summary removes flights and hotel charges (you said hotels and flights are already booked). 2) Book the Angkor pass, private guide and Koh Rong boat trips now — December is high season. 3) Confirm pier pickups with Onederz and request assistance for elderly travellers. 4) If you want a more conservative contingency (15–20%) for medical/emergency buffer, I can recalculate. 5) If you want costs converted to INR or split per person, tell me and I will provide the breakdown.
