It all starts here, at one of the docks. There are many of these large boats, each built to take around forty to fifty passengers. As just about all of the boats leave at 0930, things initially tend to get crowded in the first stretch. Entering the region of the river that traverses many of the limestone mountains.
Villages dot the sides of the river occasionally.
The typical tourist cruise boat. Crew cook lunch on the stern, while the tourists either stand up on the roof in the heat, or stay inside down below, in the air conditioning. Dining tables are inside, as that is where lunch is eaten. Actually, not an uncomfortable affair. Not sure about the bathroom facilities.
