We are staying in Porto for a week and can't decide what to do afterwards. we have 8 days to fill and not sure whether to do the coast line of portugal via train doing stop overs or head into spain. I really want to go where it's hot with nice beaches but also things to do.
If we decide to go to spain is it best to get the train from porto or fly? or get the train to lisbon and then maybe across to Valencia? or even up to San Sebastian?
