It is closer to Naples than Pompeii; I did it coming from the other direction (Sorrento) but I'd say it's about 20 minutes.
Can't answer re: the taxi, but the train is pretty easy. Once you get off the train, you'll walk downhill down a major road with the train station at your back. This road basically dead-ends at the entrance to Herculaneum in about 4-5 blocks -- you can't miss it.
There's no museum onsite.
Yes, you should have enough time to do both Herculaneum and the Archaeology Museum.
I have a lot of info on Herculaneum, included notes for a self-guided tour (having just done it a few weeks ago). If you want to give me an email, I'd be happy to send it to you.
Hello Cruisemom42,
My husband, 20 month old daughter, and I are traveling to Naples in October so I would appreciate receiving a copy of your self touring notes as well. We don't expect to be able to leave the ship really early since we'll be traveling with a small child. We'd prefer to take a more leisurely approach and get off the ship by mid morning, tour Herculaneum in the afternoon and be back on the ship by 5p. Do you think that is doable? Thank you so much for any insight. My email address is mlloftis@yahoo.com.
