Laos

Hi guys
Would love advice on best places to visit in Laos. We are two 'mature, adventurous' women trying to organise an exciting two weeks in Laos. Unusual places to stay, unusual modes of transport with a bit of walking in the country. We love meeting the locals and learning about their life and customs. Believe it best to fly to Bankok and maybe take train to Vientiane. Advice please
