Ah yes, political correctness. The all caps was a cut/paste from the website of the company; not yelling, however. Is cut/paste a 'no-no'?
I did notice that the sites I checked for tickets, just to find a price, (Last Supper, Herculaneum and Pompeii, Colosseum) each showed no tickets available for any date I tried beyond March, 2016. This site was one listed on the Milan Museum web site. Since I will need tickets for several sites in several cities, I was hopeful this might be reliable and make the task a bit easier.
We will be visiting Milan, Florence (day trips to Bologna), Naples (Herculaneum and Pompeii), Rome and then board ship from the port of Civitavecchia.
Thanks, Zoe and Priscilla and Laurel. I will check your recommendations.
