Booked this cruise because of the low price for an inside cabin. Recognizing that Conquest is an older ship lacking many bells and whistles, I realized that some wear and tear may be present; however, filth is another matter entirely.
The floors of the lido buffet were consistently sticky, slippery, and visibly dirty, regardless of the time of day. Grime was visible on all elevator buttons (when you could find a button that worked). Hair, bugs (both living and dead), and dust were common on window sills across the ship.
Dining ranged from mediocre at best to downright terrible. Typically I enjoy visiting the steakhouse, but between being swindled into paying for a bottle of wine that should have been free - our assistant waitress insisted that Carnival does not offer complimentary wine on the first night of the sailing and thus charged us, this was later rectified by speaking to the head waiter - and an inedible steak, I was left disappointed. Portions in the dining room were exceedingly small, nor was any customization available due to pre-prepared food. For example, my wife does not like cocktail sauce and prefers her shrimp plain. It was not possible to have shrimp without cocktail sauce drizzled over it since it was already prepared. Likewise, the vegetarian option was the same every night, quite frustrating for my vegetarian wife.
One of the few clean places we found on the ship. Small, as expected, but in need of some serious TLC. Several large chunks taken out of the floors and walls.
