Thanks John, yes we are looking forward to promenading down to Cascais. I went to a conference in Lisbon and, despite disliking most capital cities, found it a very pleasant place so we intend spending a couple of days there. One day site-seeing - going up by antique tram to the castle and then down again and across the centre to go up by the extraordinary street elevator to the hilltop suburb (the name of which escapes me for the moment). Another day I think Hilary will fill with visits to art galleries. I thought we would bus it up to, and around, Sintra as well on another day. I am surprised no-one is surprised at me visiting a place variously described as "exclusive", "stylish" and "classy". Naturally Hilary will meld in effortlessly; I may need to up my game a notch or two.
P.S. UBT would be clearly out of place in such a classy place. Efes indeed! I shall be drinking tankards of red wine.
