Personally I'd wander down the road and just see whats available with regards tours, should be easy to identify. I do know there is a tour driver Wayan who operates out of this hotel. If you want any driving tours, he is spot on, we use him all the time. He drives a nice clean van that will carry 6 passengers, very polite, good english and has a nice sense of humour. But he wont be able to organise your cycling, snorkelling etc, he is more a driver.
