I had fun on the Conquest (wk of 3/25). It may be different expectations and/or what people were looking for. I didn't have problems with the staff I encountered.
I think with a ship this large there are going to be many different experiences so you have to find the cruiser(s) you relate to. I.e are they looking to do things with their kids (ages of those kids), more as a romantic getaway with spouse, fun to be had with lots of other cruisers.
I know it was hard for me when I was reading reviews to find which ones were going to predict how much fun I'd have.
As someone who traveled with her kids and grandchild and someone who just wanted to relax, take in a few shows, not use the bars much, I had a great time. I also ended up with a quiet floor so this worked out good for me. Examples: Now if I had noisy neighbors, I would not have been a happy cruiser. Note - I had a room that was a little on the warm side, but this suited me. I don't think my daughter was thrilled as it wasn't cold enough, I hate AC when it makes me cold. Many would not have happy, but for me it worked out great. :p
