Hi, Karin here. We did just about half the Portuguese route in May. Started in Valenca/Tui and made Santiago in 6 days...allowing for a relatively slow pace to give us time to adjust to jet lag. So yeah..the whole route from Porto in two weeks...doable. We spoke very little I'm ashamed to say

BUT I do speak German...and that got us thru in two rather interesting occasions! With few key phrases...you should be able to get thru. People were very very helpful, kind and I'd go back in two seconds if someone handed me a ticket and said go! Stop home long enough to gather a few things...and GONE! The is a delightful little restaurant in Porrino...the alburge was memorable...ahhh....Ill be smiling the rest of the day now...
