Loved the cruise. The service was excellent. My wife and I booked room 716 which did not come with butler service. There was no need for a butler because anything we asked for was delivered timely and with a smile. Initially, we were concerned because we are both 30 and thought we would significantly younger than the rest of the cruise. There were several other young couples so it was no big deal.
Day 1 - The weather was bad on several days of our trip. Yes we did go to the port of Naples in lieu of the Island of Capri. However, had we not, we would not have been able to get off the boat because the seas were to high for the tenders. Naples is a 22km drive from sorrento and thus added 20 minutes to the tours. The guide in Pompeii was excellent. Our tour group had maybe 15 people.
Day 2 - Positano was amazing. Disembarking the ship on the tenders did take 30 minutes simply because the seas were rough in the morning and it took longer. Can't control the seas.
