According to Celebrities web site, Horizon entered service May 1990 and was refurbished in October 1998.
Gram and I sailed on her in November 1998 , everything was like new and there were still workmen aboard doing things like building Micheals Club and laying down a new pool deck surface.
It could use a nice carpet in some bright colors and nicer artwork.
The dining room food the best I've had so far on any ship.
Word of advice: Beware of the cabins on Deck 6 under the kitchen galley......very noisy, you will not sleep and the engines are pretty noisy down there as well. Stick to the upper decks.
