We tried their Mt Vesuvious tour. We were not informed in advance that the entrance gate to the top could be closed due to the weather. It was so windy there and even snowing a little. The gate was closed. I think they had a way to know about this. Bad luck. Another thing, this is bothering me a lot, the lady in Pompeii office said that Herculaneum is far away from the nearest train station, it takes 30 minutes walk. She was trying to sell us the tour for that. I found out later that the ruin is just 10 minutes walk from the nearby train station.
