I'll think hard about taking a Carnival Cruise again

I've been on several different cruise lines & Carnival has always been a disappointment to me.  Other than our room steward, The service staff seems lazy & preocuppied.  The buffet was so so and boring serving the same ordinary things repeatedly.  We took a bus tour of Nassau that, if you were a non-drinker, was boring and senseless.  Our balcony room was clean especially on our 2nd day after they washed our windows.  Our final bill included 2 charges we were unaware of but after checking with guest services was told it was the gratuities for our dining & room services (we had already provided cash to select employees)  The specialty restaurant was excellent, the food & the service should have been what the entire cruise included.....at least that was the way it was in past cruises.  My last cruise was only 3 years ago on a different line, so things couldn't have changed that much.  Our bus tour of Freeport was excellent & probably saved the whole cruise for us along with the night in the specialty restaurant.  "Faster to the Fun" was an extra feature which made getting on & off much easier, & not having to wait on line for guest services more palpable.
