We actually started in Lewiston and went to Portland and it was good trip. Boat is great and food was very good. Would have like a few more "low calorie" options. Entertainment left a lot to be desired. Also the shore excursions need a little work on the timing so you do not spend so much time on the bus and at one stop most of the stores were closed as it was a Sunday. In my mind, it was an important stop. Historian was great and had so m much information about the area and both the Oregon Trial and Lewis and Clark Expedition that was not in most books you read. We would have liked to have arrived in Portland earlier, and that was doable and been able to see Fort Vancouver. I have suggested that to them.
Washer was perfect, but can not guarentee that fore everyone and very windy so bring clothes for that.
