This is a nice place and the boat ride starts from Rajahumndary or Badrachalam. It if worth to start from Rajahumndry as the boats will not be crowded and you can enjoy a lot,. I have been there during Dilwai 2013 as my family yearly outing with my family (father, mother, brother and sisters along with better halfs and kids). All of them enjoyed a lot and the best time to visit is oct to dec. Do let me know if you need any help in bookings.
We have stayed there in the huts for one night and best thing is the owners of the huts is very co operative and helpful.
Never had these hotels 50 years ago and I lived in the area for many years
