Southern Laos - Tad Lo, Attapeu

2 adults and a 2 year old will be goin to Southern Laos for 7 days in December.

Will be travelling to Tad Lo Waterfall in Salavan Province in Southern Laos,and I'm looking for a contact number for the Saise Green House? Has anyone been there?Is it necessary for me to make advance reservations since I will be going over Christmas -New year, or do I just need to show up to get a room? I'm thinking about making a reservation but I can't find a contact number.

Does anyone have any other advice about travelling with a 2 year old in Southern Laos? I am thinking about going to Attapeu Province in the far Eastern corner next to Vietnam, but I'm not sure of the road conditions, or if a young child could handle the journey from Pakse to Attapeu.

WHat about Si Phan Don islands? Is it worth going to, or just skip it? I only have 7 days, and don't want to try to cover too much.

Any recommendations for lodging in Pakse, Tad Lo, or Attapeu?

Last question is about visas. Does a Thai adult need a visa to go to Laos? What about a Thai child of 2 years?

Thanks for any advice or suggestions.
