City

You should stay in Laos only one day with seeing Patuxay, That Luang, Sisakhet Temple.. You shouldn't go to Buddha Park cause it's so far from centre, about 27 km. You shouln't go to Nongkhai or Udonthani too because there is not any high quality goods in the supermarkets there. But you should stay in Luang Prabang for 3 days. Luang is a very quiet, romantic and small town.
