We done Pompeii on our own. Make sure you get your tram ticket from the kiosks before getting on or you will incur the wrath of the inspectors as well as a fine. Be careful at the central train/bus/tram station as the pickpockets are waiting! Not a nice place to be.
I have never been with Island so I don't know the quality or price of their excursions but for all of those ports you have mentioned I would explore without the official tours. Get as much information about the ports from the web and the official tours and then decided what you would like to see. It's invariably cheaper DIY ....regards Nei.
Thanks for that Neil. We normally do do our own thing expecially round carib & asia etc (cheaper countries) but this is the first time we have gone to a euro country and as the £ doesn't travel too well .........
