Ok, I know this is a long shot, but...
I'll be in Naples in March and would like to book a tour of Pompeii with one of the guides regularly recommended in these forums. Expecting it to cost a few hundred dollars, it's a hefty price to do solo. But maybe other forum members might be in Naples/Amalfi, and be interested in making a small group?
I arrive in Naples on the 18th and leave on the 23rd, so could do any of the four days in between.
