This was my sixth cruise overall and my fourth cruise with Thomson but first time on the Celebration. The ship is dated and many passengers complained about vibrations and noise but our interior cabin on one of the lower decks was fine. It was spacious, clean and pleasant. I think it was passengers on the higher decks who complained about the noise and vibrations and people in the cheapest cabins on lower decks were fine so it really doesn't pay to splash out on a cabin on a higher deck on the Celebration.
Overall it was a pleasant stay on the ship. The staff were wonderful and the food was good with plenty of variety. The entertainment was good apart from the British comedian who was not funny at all unless you were completely drunk and would laugh at anything anyway.
I used the gym a couple of times and found it to be basic but adequate
