Needs improvement

Ship is old and desperately needs updating.  Rooms are ugly and not very clean.  Navigating the ship is confusing as to get to one restaurant you must go up one level and come down one level on the other end of the restaurant.  Of course you don't realize this until you arrive for dinner and have to make a detour.  Went to hear the main band on 9th level two nights in a row, both nights they had 'technical

 difficulties and we left after one hour waiting.  Very limited sugar-free food.  Limited to one dessert each day, look like same cake with a different flavor most days.  No sugar-free ice cream.  Charge and a first come first serve (with a limited supply) for cooler for room for insulin.  Mustering drill was a joke.  We waited in a lobby area approximately 45 minutes while they tried to round up passengers.  We asked if it was always this way and the reply, was in a very negative tone, like mind your own business.  Then we were marched up a flight of stairs under the boats, 5 deep to the railing, no words were spoken regarding the boats or this is where we should report, and then dismissal.  Worst we've ever experienced.  So bad in fact, that two 'Diamond' couples said it was terrible.  This was our first and most likely our last Carnival cruise. 

Oh, one of the first things we encounter was when we entered the ship from gangway - many people gather in area where large bar was located, no direction of asking if we needed help or looking to see what floor we needed to be on, and where we saw cabin signs, large pink metal doors were closed under the signs so we were not sure if we were to enter through those doors.
