Fourteen days for a deep, unhurried exploration of Bangkok and nearby escapes.
Days 1–7 follow the one-week itinerary above; add an evening Muay Thai match, a proper spa day, and a second day-trip to Kanchanaburi.
Days 8–10: deep neighbourhood exploration (Thonburi canals, Dusit, Lat Phrao local life); Day 11–12: overnight to Hua Hin or Koh Chang for a beach break.
Return refreshed; revisit favourite food spots; a sunset river cruise; extra time at Bangkok National Museum; shopping for gifts.
Two weeks is long enough to feel like you live here — build in one completely free day per week with no plan; the city reveals itself when you're not trying.
