Would you please recommend a day tour to Pompeii from Rome.
I have had good luck with Viator Tours. Just google Viator Tours and put in the question area that you want a tour from Rome to Pompeii and they will show you several in different price ranges and length of time gone.

We did this one in November and loved it.

There were 5 of us on the tour. The Pompeii guide was fantastic. He came from a family of Pompeii guides, so had grown up with it and was very knowledgeable. His tour included a newly uncovered area that hardly anyone has seen yet.
In 2019 we did a day tour with City Wonders. It was more of a big bus style experience, compared with the RS Tour we had just finished. But everything ran smoothly and we also had a stop to hike up Vesuvius and a decent pizza lunch. The larger group was split into two smaller groups at Pompeii, where we had specialized guides. Overall I’d recommend.
