While it looked romantic on the slow ferry boat, it took too long. Some folks who went with the ferry decided not to come back with it. It took almost 3 hours on the ferry boat, an eternity considering it took that long to return. The guide book recommended the speed boat which was what we took. Even the speed boat, the journey was one hour each way. At the ticket office we were matched with others who wanted to take the speed boat. Once a group of enough people is found, the boat leaves. We traveled some gorgeous scenery.
