Celebrity is my favorite. I started trying other cruise lines to get a better view of what I liked and didn't like.
Princess has the best entertainment (just my opinion), Celebrity the best food followed by HAL. However, opinions are like a _s h _ _ _s, everyone has one. There is no such thing as a bad cruise, just a better one. Staff, people you meet and ports visited all play a roll in the enjoyment one has on a cruise. Cabins on some ships are larger than others (in the same category). I have started booking inside cabins because we spend NO time in the cabin and I can save a lot of $$$ booking an inside (more $$ to cruise more often). Again, just an opinion. Others like to book the suites and travel first class.
Put me on ANY ship and I will have a wonderful time, I just love to cruise!
Celebrity is just my favorite!!!!!!!
