Sailed with Carnival many times, never complained.  This cruise however was my worst cruise ever.  And this would include all other cruises, on other cruise lines.  The staff was overwhelmed.  I sat with dirty dishes on my table for at least twenty min.  By mid week I started asking waiter's to please take my plate.  I even had a waiter stand on line and tell me to wait for dinner lunch was now over.  With people on line and food still out I couldn't understand why I couldn't get a piece of fish.  Also before breakfast was over they turned off the orange juice dispenser. I asked the bartender for a glass of juice, he gladly gave it to me and asked for my room pass to charge me.  I said, I will not pay for juice thats free.  He said its only free in the morning, this is the afternoon.  And with that being said, he took it back and emptied it in the sink.  The cabin steward left my cabin door open twice.  The omelet guy let people order four to five omelets and a time.  So my wait for a omelet was at least 35 to 40 minutes long.  You also couldn't count on a cup being out for coffee and a glass out for water.  Staff walked by and acted as if they didn't noticed there weren't any.  I should be happy because sometimes a found a cup, but then it wasn't any coffee ready.  I could go on and on but I won't.  Just glad I'm back home.   Wow and I used to love Carnival.
