We moved from Hawaii to Texas last summer, so our trip included an airplane ride from Honolulu to LA. We stayed 2 days in LA while we waited for our car to arrive then headed off on our way to Austin, TX. 2 dogs, 2 kids and 2 adults in a Toyota Sienna with LUGGAGE! At the time we had 2 small dogs, a pug and a cavalier. They travel well, so we did not have to stop any more often than the humans needed to. The hotels we stayed at were ok with us leaving them in the room as long as they were crated. BUT I must admit, it was hard to find accommodations for multiple dogs. Most of the places only accepted one per room and MANY have weight restrictions. SO be sure to call ahead. Several places told me I had to book 2 rooms! And NO, we NEVER left the dogs in the car, EVER. We just planed our trip so that we could check into a hotel before venturing out to get food other than fast-food.

In February we took a 13 hour road trip to Angel Fire from Austin, this time with 3 dogs (we rescued a Husky Puppy) and even the puppy was fine. We made sure to walk him before we started the journey, and at every stop along the way, but for the most part, they just sleep. Just like the kids, the motion of the car seems to sedate them a bit. Maybe I'm just lucky. Our dogs don't seem to have car anxiety like some do, but we did make sure to bring toys and treats, and make a nice comfortable spot for them that they could lie down, and get up and change positions etc.

We would take them with us everywhere we go if there were more places that accepted multiple dogs.
