The ship.
Our previous cruise was aboard the Astoria (Cruise Maritime Vessels), a good comparison being about the same size. The Astoria is a bit smaller in dimensions and weight, but has a larger draught. The Pearl II has a knot or two extra in top speed, and carries 45 odd fewer passengers (512 vs 556). Both ships give the benefit of small ships to those that prefer this; no great hikes to get from one place to another, plenty of sitting places, no long queues, interesting layout that feels like a ship rather than a shopping centre. The Pearl has gangway entrances on two decks and when the gangway was used from deck A it never seemed as steep as Astoria. Perhaps the decor on the Pearl was marginally better (say 9/10 rather than 8.5/10), but this depends on personal preference so lets say they are equal.
We had an inside cabin on A deck, which was small but adequate. The shower is a bit tricky until you realise the doors open both ways; inwards and outwards. If you open them outwards, it is a tight squeeze to get between them. If you open them inwards, it isn't easy to close them behind you. The trick is to open one inwards and one outwards, then it is a piece of cake. Having now experienced Saga, we have booked on Saga Sapphire for next year, "Stylish Scandinavia", visiting Denmark, Sweden and Norway. We were told our cabin 6576 on deck 6 will be nearly twice as big as our current one on Saga Pearl II. Our current cabin (311) is not in the best location as it is under the Discovery lounge with lots of bumping when they rearrange the seating for afternoon tea, and thumping from the bass when they have music during showtime.
