I hope you have a great time in Pompeii. I wrote a review of my trip in October 2015. If you stay at the same hotel in Pompeii as we did, it's an easy walk back to the site if you want to,spend some more time there to explore independantly. Also, on our trip, we spent the morning on a guided tour, then had the opportunity to spend more time before walking back to the hotel. Don't miss the optional excursion to Herculaneum, to get another perspective on life before the volcano erupted. There is no shade at the Pompeii site, so take a sun hat, use plenty of sun block, and take water with you. You will be mainly walking on cobbles, so comfortable shoes with non slip soles are recommended. Anything else, just ask.
