I am planning a trip to Cambodia, and Vietnam in the latter half of this month. Only recently I came to know about Luang Prabang, and might be able to manage a one and a half day stop over there. Is it worth going there for such a short duration. The tentative itinerary is mentioned below. Please have a look and advise.
Day 1 - Arrive in Luang Prabang around 6:30 pm
Day 2 - Take a guided tour or a reserved taxi, and see the major attractions within the town.
Day 3 - Return flight departs at 7:15 pm. Are we going to have enough time during the day to visit the Kuang Si falls? If yes, how much should a private taxi cost for going and there and returning to the airport?
Also, for attractions within the town will the guided tour be better, or should I take a taxi. How much should a full day taxi cost?
