Has anyone done the Perama boat that leaves from Senggigi beach and on to Trawangan? If so, how much, what time do they leave a return and are they safe? how long does it take? Dont really want to go thru the hassle at Bangsal Harbour or ride in one the small prahu's. Any alternatives? I know can get a fast boat but seems a lot of money for such a short way. Any other alternatives? Thanks in advance guys.
