One time in Alaska, we drove to Haines and spent the week of July 4th at the Oceanside CG which is right on the Lynn Canal. It was great! I was interested in the ferry so we drove to the nearby terminal one day and spoke to the the agent on duty. She was so very helpful. I had no prior reservations. She put together a really neat trip for us, a 34 foot class A coach and a saturn toad. One segment to Juneau with a three day stay. The fast ferry to Sitka with four day stay and a overnight trip to Ketchikan with another four day visit. The final leg was a quick trip to prince Rupert, BC.
We had our dog with us and he was required to stay in the coach on the car deck. It was not really a problem and during the overnight trip out of Sitka, when the ferry was stopped at Petersburg and Wrangell we could take the dog off the ship for a walk. I learned a lot about following directions when driving onto and off the ship as well as backing my rv long distances in the car deck. The employees of the AK ferries are great and the four ferries that we took sailing south through the inside passage was high point of our journey to Canada and Alaska.
