A "thank you" and a follow up.
We based in Sorrento for 4 nights and had a great trip. I cannot recommend Il San Gaetano pensione in Sorrento strongly enough. DM me for details or check out booking.com
We arrived Naples on the Palermo ferry to a beautiful bluebird morning and took a taxi (I had to barter the price a bit but in retrospect I was happy to have "splurged" vs lugging our packs on the metro/busses. Since we got to the Archeological Museum early, we spent an hour sharing coffee and chatting with a local student at a nearby pasticceria before heading over as the museum opened. We stored our bags at the cloakroom and spent the morning it this ABSOLUTE GEM of a museum. Honestly, this should be required for anyone heading to Pompeii. It really gives you fantastic background before visiting. We took the metro from directly under the museum to the train station and then on to Sorrento.
Blue Grotto
We kept an eye on the weather and a Facebook page dedicated to announcing Blue Grotto openings. For much of the early part of November it was often open. From Sorrento, we booked individual one way ferry tix online to make the most of our visit timing. Having read previous posts I saw that one of the Blue Grotto operators mentioned here (I'll dig up the name) had a few people on a boat getting ready to depart so I snagged a couple seats. The ride was scenic and comfortable. It wasn't a "tour", it was just a direct shot to the cave mouth and back. We arrived just as another boat was finishing up so we got in pretty quick. It's a hoot... from the floating cashier to the hammy, tip-cadging rowers singing for their guests. It was a bucket-list item for my wife and she loved it. I loved the whole crazy experience of it but if I had died without experiencing the Blue Grotto, my life would not have had and empty void. So don't feel sad if you get shut out by weather.
Capri itself is really beautiful and charming in a very polished, and very expensive way. We happily paid €13 for spritzes at the panoramic bar atop the funicular (€3for the drink €10 for the view) and walked to the Giardini Augosto for some different beautiful views. It was a nice day but the early sunset does shorten your time a bit. I would have liked to go to Anacapri.
26 years ago, we used the Amalfi Coast to "take a vacation from our vacation" as Rick said at the time and it was perfect for that purpose again. Slow pace, great dinners, beautiful vistas... yup.
