Bangkok transport works best when the hotel is near a useful BTS or MRT station and river transport is used where it makes sense.
Use BTS and MRT for central corridors
Rail can reduce time lost to road traffic on many common visitor routes.
Use river boats for historic districts
The river can be both transport and sightseeing when visiting waterfront areas.
Use taxis selectively
Taxis are useful for areas beyond rail lines, but traffic can affect travel time.
Check airport transfer options before booking
BKK and DMK serve different routes and can change the easiest hotel-transfer plan.
