Why? Were you on one of the Herd cruise lines where they pack in the passengers? Celebrity has limited number of passengers compared to other cruise lines. I never felt crowded the whole time I was aboard. Easy access to everything including the jacuzzis.
If you like buffets, you might like a cruise ship.
If you like public pools, you might like a cruise ship.
If you like floating by paradise but not staying for weeks in it, you might like a cruise ship.
If you don’t know what Norovirus is, you might like cruise ships.
It’s the McDonalds’s/Wall Mart of vacations.
The above is my opinion, why i don’t go on cruise ships. I also don’t like Vegas, for the record. But hey, many like cruises and Vegas.
