Consider booking flights or taking domestic flights to save travel time between destinations. Private transfers, taxis, and car rentals are also available, but it's advised to check availability and pricing beforehand. Travel costs may vary based on mode of transportation.
If you have more time, add a day trip to Krabi or explore Bangkok's vibrant nightlife. If you have less time, consider reducing the stay in Khao Lak. For a more budget-friendly trip, opt for street food and public transportation instead of fine dining and private transfers.
