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.
We decided to pay the supplement upgrade on the all-inclusive drinks package and we felt it was worth the money as you would have to pay for cans coffee etc on the normal package.
The entertainment on the ship was good and always plenty to do, the ship and anchor is popular along with the theatre and these tend to get quite busy but they have lots of bars around the ship to choose from.
We have cruised with Tui before and will continue to do so
Balcony cabin was good with large external area
