You can walk the grounds including outside the Wat for free - going inside is what will cost you. Behind the palace is a small collection of cars donated to the Laos King. Be sure to check it out.
Attended the Royal BalletTheatreperformance. It was interesting to see the traditional arts. Performance was 1hr, cheapest tickets were 100,000. But for 150,000 you got the front row & comfy seats.
It is forbidden to take pics inside the museum, once you try , security would ask you to delete it. Outside is really beautiful, if you have time- one of must see in Luang Prabang
Very strict dress code, make sure you cover up correctly. Closes for a long lunch so make sure you plan your trip well. Walking around the gardens is possible over lunch but there is not much to see.
Skip. No pics inside, there are about 4 rooms to walk through, and you can see the same style of mural at Wat Xieng Thong. Not worth the entrance fee or hassle (they're strict about bags and clothes).
