Hi, my name is Jo. I'm looking to move to Portugal from the US in the next 3-4 years. I would like to get some suggestions for places along the Silver Coast good for a single female. Towns large enough for social activity, etc. and close to the beach but small enough not to attract the major tourist hoards. Preferably where a car won't be absolutely necessary. I'm thinking somewhere along the train line south of Caiscais (and a little cheaper). Suggestions would be greatly appreciated.
