transport from araujo to vilarinho +vilarinho to rates

Hi, I'm trying to workout "transportation options" along the Caminho using perhaps Porto, Ponte de Lima,Valenca/Tui as "bases" and bus/train to and fro from end/start of each days walk.[with day packs hope to follow as close as possible the 5 day option for walking distances set out by the online Camino Portugues. Would appreciate all/any advice/suggestions THANKS :? PS..This is to avoid the possible crowds in the albergues,and at these larger? towns a bigger choice of accommodation.

In my :? state I perhaps didn't make it clear what info I realy need! What I really would appreciate is help/info how to find the transport options/connections for these towns [or others] to enable me to walk the route as mentioned above.[not only,but including the subject heading] once again thanks
