My wife and I are around 40 yrs old and travelled without children - for those looking for a romantic vacation like us - we recommend stay away from the conquest. The ship public areas and facilities are far too small for the 3000 passengers they pack onboard. This ship is the same length as the spirit class ships which only hold 2000 passengers.
We always had to hunt and circle to find empty loungers around the pool - one time i even untied a stack of loungers and broke them down so we could have a seat. Children run wild and free around the pool decks, the hot tubs are more like kid stew than kid soup.
Essentially all of the bars are on deck 5 - these bars are no larger than on the 1500 passenger holiday. My experience on our four cruises is that karaoke has the highest attendance. The conquest has karaoke in a bar that according to my wife is the size of the kitchen and living room in our 2000 sq ft house - i seriously doubt there is seating for 100 people in this bar.
