Don't know about rock stars or football players, but sails from Bayonne are full of families and with lots of kids especially with the "Kids sail free promos." On recent August 20 Oasis the ship was filled to the gills and sail on sea days, the 3 pools were filled to capacity with adults and kids alike. I believe the capacity listed is somewhere in the 20s, but the pools must have had more that 50 in the water and many more surrounding the pools. They were hot days.
Remember, the suite population is minor to the overall ship's capacity.
