Ventura Ca to Seattle Wa?

We've taken the coach on the ferries many times. Very easy. Book in advance when you get two three days away. You will need to un hook the tow car before getting on. Again, no big deal. In fact it's fun! Depending on which ferry company, there is parking on the street or a lot close to terminal. We pull in and sleep with other rigs as you may need to be in line around 5 or 6AM. If you have a pet, they can stay in the coach. Be sure to bring all pet health records just in case. Never been asked for them but have been told on their websites to have available.
