Now, as we have sorted the places to stay, lets talk about the commute. You can easily use the public transport for your to and for commute to the river. For river crossing we have ample of boats at frequent intervals.
To commute withing Hippie's Island, you have option of self driven bikes and gear less scooters, they charge you around 250-350 per day and trust me that is the best way you explore the place.
You can also get private Rickshaws for a day, for sightseeing the tourist spots for around 2000 - 3500 per day. But I believe that is bit too much and you lose your independence too.
You can also explore the place on foot, I have seen loads of people doing so. Or through Bicycles
