We did Amsterdam down to Lisbon and back, with stops at Vigo, Spain, Bilbao, Spain, Le Havre, France, Southampton, England and Guernsey.
We twice went ashore and explored on our own, twice used private small-group tours NOT booked through the ship and twice used ship-booked excursions. We are still new at cruising, this being our 3rd cruise, but we are learning fast. We have no desire to ever book a ship-booked excursion again - overpriced, overcrowded, few stops, most of the time wasted waiting for 70 people to get on and off the bus.
We are very glad we tried booking our own private excursions. We used We Hate Tourism Tours in Lisbon and Discover the South in Southampton. We were delighted with both. It is worth paying extra for the customized, small-group experience.
Lovely cabin, useless shower curtain, drawers had to be blocked with clothing to stop them banging during the night, excellent housekeeping, excellent cabin steward, excellent room service, nice balcony, needs mesh as openings are too big, would not let a child out on that balcony.
