maryh, please include some Portuguese poetry in your trip planning. Fernando Pessoa is one of the foremost, if not THE foremost Portuguese poet. To give you "a sense of place", about the Alentejo, this is what he wrote:
**Alentejo Seen from the Train*
"Nothing with nothing around it.
And a few trees in between
None of which very clearly green,
Where no river or flower pays a visit.
If there be a hell. I've found it,
For if it ain't here, where the Devil is it?" 1907*
Please read about Fernando Pessoa, who wrote poetry, essays and fiction, as at least five distinct individuals (which he calls "heteronyms"). You will learn a lot about Portugal!
