Gosh, quick replies! Thank you, all, this forum seems to be a great resource!
I am doing lots of reading before the trip, to be somewhat prepared. I have Rick's guidebooks for Rome and Venice.
I realize seeing Pompeii is a long day, but my husband and I are really keen to see it. I was just wondering what the Herculaneum visit is like.
We have stayed at AirBnB's many times in the US, and find them to be very nice. I'm not sure how it would be in Europe, but I would think they have the homey feel to them, at least. The website for AirBnB really screens the hosts, they have to meet certain criteria, and give a lot of detail. They are usually cheaper than hotels, and I have not been disappointed at all in the accommodations. The ones we have booked for this trip are very conveniently located, also, close to the main areas of the cities.
I was last in Europe in 1989 (was in Paris when the Berlin Wall came down!), so it has been quite awhile.
