Where do retired Americans Abroad live, or want to move to? [View all]

My husband and I are retired; he has dual citizenship (US and Irish). We've spent a year in Spain, time Portugal, England and have traveled throughout several countries in Eastern Europe and a few scandanavian countries. At the moment we live in Central Oregon (a lovely place!), where our oldest daughter (28) and son-in-law (29) live.

We have talked a lot about moving abroad -- maybe to Portugal, Spain, or should it be Costa Rica? Mexico? The why's are primarily political (duh) but what holds us back is that we truly love our daughter(s) and SIL and want to be a part of their lives. So, we've thought about spending several months abroad and having a place to land here in Oregon...

So my question(s) are this?
1)Where do DU Americans Abroad live, or want to/plan to move to?
2) Where do DU Americans Abroad recommend folks who are retired (but with plenty of spunk) live?
3) For DU Americans Abroad who are abroad, how do you deal with your family/friends back in the US that you DO want to be a part of your lives?

Thank you so much!
