Thanks Tsastor!
Okay, maybe we won't do any day trips for our first visit to Lisbon, then. I am cool with that......would rather get to know the city itself well, I think. Wish we had more vacation time so we could stay longer. That four-letter word 'work' seems to always mess up things!
Amarone--Would love to go down the coast, we'll see if time permits, or if we can go back someday....thanks so much for your advice!
