We arrived in Naples late, around 6:oo PM on Saturday 23 September after a long and, needless to say, adventuresome train trip from Viareggio. We had planned to take the Circumvesuvian to Sorrento, where we were booked in Hotel Desiree. Taking a taxi, although it was 100 Euro, was probably the best decision we made the entire three-week trip! Traffic was literally bumper to bumper from most of the trip, so we feel we got a bargain in the taxi. Sorrento is the very last stop of many, maybe twenty or more, from Naples with Sorrento being the very last. Further, you will likely be toting bags for which there is little provision on this train except to stand with them for security in the "vestibule" of one of the train cars. I agree with a previous poster and with Rick Steves that this train, and especially that time of night would be frightening at best. We did take it during the day to Pompeii with no problems.
