we are a family of 11 traveling from conca dei marini with a tour guide to Pompeii with a 9:00 AM pick up.....what is a good estimation of time in Pompeii and what else if anything would you suggest seeing on the same day returning to our villa around 6:30PM
I suggest the Archeological Museum in Napoli - it contains many of the objects from Pompeii.
To have a reasonable look at the site with a guide will take around three hours but you could easily spend all day there.
Pompeii itself does not have much else to offer.
I agree with a trip into Napoli to the Archeological nuseum if time permits.
Or you could go up Vesuvius.
Three hours with good guide would give a decent overview of Pompeii but easily spend six hours or more you really wanted to look at it in detail.
