We chose the Explorer as it was only a four hour flight from the uk you are guaranteed some sunshine in the canaries.
We had a had a balcony cabin on 9 deck and the balcony was the biggest we have ever had it had a lounger two chairs coffee table and hammock. Shower was good as it has a door rather than the usual clingy curtain. The decor was of the usual standard you get in cabin and no complaints.
The food on board was good and as with the majority of cruise lines you have to pay supplements for speciality restaurants for the better quality food.
Balcony cabin was good with large external area
