Had a 1 night stop on a 1-star houseboat/ raft late last year at Sai Yok National Park. River and falls flowing great. Like to go again. Googled that June/July best time as states 'rainy' season. Is this true? Anyone been recently or from area. Didn't think much rain yet.Any clues as to best time to visit greatly appreciated. Other advice welcomed also - accomodation etc.
