We had a great time on the Jewel. Three great ports, very friendly and helpful staff on the ship. Very good guides on the shore excursions. Enjoyed the Free Style dining option and the view from Tsars Palace. The Russian acrobats were incredible and the rest of the entertainment was good. Ship is very clean and well maintained.
The only complaints were that the food wasn't always hot both at the buffet and the main dining rooms, and the bathroom is a little cramped.
