Hi, we are in the initial stages of planning a holiday next Easter to Laos and Cambodia. We don?t want to take anti malarials so are thinking of sticking just with luang prabang in Laos then flying to Phnom Penh to go to Kep, Kampot and on of the islands. Can anybody recommend the best / cheapest way to fly from London please? We don?t mind which order we visit in. How long would you recommend in each of the places in Cambodia? Thanks
