I choose this because it featured a seminar I wanted to participate in and because of its ports of call (especially Gibraltar). When we started planning our excursions about 3 months prior to departure, the expansive Gibraltar tour was waitlisted and never re-opened. I find that to be unforgiveable and unforgettable. But we booked a private tour through Viator and it was the best tour of our trip, and less than half the cost of a lesser quality ship excursion.
While many will like the food and dinner requirements (specific time reservations, more formal dressing and very formal on all sea days), we take cruises to experience the ports of call, not to have formal dining experience. So, for us, this is not a positive. Further, we thought the "Tastes" specialty restaurant was way over-rated: marginal food and served in a pool cabana setting which was not a very good atmosphere.
Getting on and off were very good experiences. Same for access to excursions; and the free water bottles on the tour buses was very welcome and not standard with our cruises.
Nice, but only 1 US outlet and 1 Euro outlet. None in bathroom.
Visited Mont St. Michael; very impressive construction and good guide.
Full exploration of wonderful places including the book store that inspired HArry Potter novels.
The Estoril coast was a pleasant surprise, even though we were only able to do a drive thru.
