We chose this cruise because of the itinerary and we had two amazing cruises on marella discovery pre COVID. One of the things we loved on discovery was the amazing shows in the theatre every evening, the "shows" on Explorer were dismal, every night there was six very average singers attempting to put on a show on an empty stage. People were leaving the theatre every night, it was embarrassing for the performers.
The bed linen was worn, it was more like a badly run down two star hotel room.
Waiting to get served in the bars was another problem, there seemed to be not enough staff on board.
