I am moving with my two small dogs to Vilcabamba and will be flying into Guayaguil. I don't really want to fly them any more than necessary. Can I take them on the bus to Cuenca, stay over a couple days, and then go again on the bus to Vilca? Or would it be easier to hire a van? I have to do this the cheapest (and easiest way on the dogs) possible. Thanks.
