I have not sailed on the Spirit, but I did sail on Luminosa this past June. We LOVED that ship. It was meant to be a relaxing trip and it stacked up as the best trip. If you are looking to be busy, busy on the ship, I don't know if that is the one for you. We don't like the party atmosphere on most ships, so this worked great for us. We've already booked another trip on the Luminosa for this reason.
