Very Disappointed

Our first cruise (my husbands retirement present) we were so excited. When we first arrived everything was just great after all Holland America belongs to one of the largest if not THE largest cruise lines in the world Carnival Cruise Lines..
It didn't take long for the shine to wear off our cruise, the stench coming from the toilet was unbearable, each time the toilet was flushed the odor filled the bathroom area.
A lady who was in the cabin a few doors down from us was so angry about something, I'm not sure what it was, blew a tantrum and changed rooms from the 6th. floor to another floor, oh yes we paid for and were in the upper veranda ss rooms.
And then it happened, we had to step on and kill a COCKROACH yes a COCKROACH and believe me it was a big one. How would you feel if you opened your upper veranda ss suite room door and were confronted by a cockroach. After killing it we took a picture of it and brought the photo to the front desk. She actually came up to the 6th floor, confirmed it was a cockroach and picked it up and took it away, she said she would have our room scanned and cleaned for any other roachs that may be lurking in the dark.
Then the nightmare began, the front desk manager a young lady by the name of Nancy just about came out and said we had brought the COCHROACH aboard the ship. She did everything in her power to pooh pooh the incident away.
Then she said she wasn't going to offer us anything for our troubles because she didn't want to insult us, and if we wanted to take this incident any further we should talk to their head office, and that is that.
That was our first cruise experience, we won't be taking our chances with any of the Holland Cruise or any Carnival Cruise companies again.
