Whisper May 9th Sorrento tour - share?

We are on the Whisper May 5th from Barcelona to Rome and we have booked a private tour for Sunday May 9th with Marcello Maresca for Pompeii and the Amalfi Coast. As we are only 3 people, and he has a minivan (accommodates 6) if anyone is interested in sharing please let me know.

ppiew - my sister and I are on the same cruise and were planning on taking the Ships tour, however, private tour might be preferable. Could you let me have some details - my email address is gail@imageprojects.co.uk
