I Just returned from my first and maybe my last Carnival cruise . I was on the Horizon 8 day to Puerto Rico , Grand Turk, and Dominican Republic . Let me start with a positive note getting on the ship was great from there everything got worse. I had made reservations with the Steak House online before going and also purchased beer, water and excursions. When I got on board I stopped at the steak house to confirm my reservation only to be told I didn't have one. I let it go thinking maybe there was some glitch. Then I went to my room and found my water with a note but no beer so I called Guest services the phone rang for 15 minutes before someone answered and told me I had never purchased beer . I explained that I had and she asked if I was able to prove it and thank God I had the confirmation. I was then told they would have to do an email inquiry. I waited 5 hours before walking to Guest Services to only be told I hadn't purchased it so I showed her my confirmation and about an hour later I got it. Next, I had received 3 of my 4 bags my husband and I bought with us. I kept asking were they bringing more bags and was told yes , yes but after 5 hours waiting I started to worry so I started walking to guest services to see if they had it when much to my surprise a man was bringing my bag into the hall from his room . He told me the staff had put it in his room . I was very upset since it had my personal items in it . My husband and I purchased bar cash so we went on the top deck and ordered 2 drinks , later on that night I looked at my account and found they had charged me for the peoples drinks behind me as well as mine . I had to go back to Guest Services to get them to remove the charges. I played in the casino quite a bit so I was able to get a drink card pretty quickly . I only ordered 1 drink while in the casino and was made to feel like I was a thief. Gentleman took my order then came back and realized I should not have not been charged so he went to get it taken off. The casino host then came over and picked up my card and asked me if this was my card and if I had taken it from someone . I was floored , I hardly ever drink so I would not have stolen anything like that . Needless to say I didn't drink there anymore . She asked me for my name and said spell your last name . It was very embarrassing . My husband and I are very early risers so I requested room service every morning 5 to 7 am . We also go to bed by 9 pm so we made sure the tag was on the door by 9 . One morning I am waiting and waiting for my coffee to come so I finally opened the door and it was still there no one picked it up. One evening it too me 2 hours to get my food . No one walks around and asks if you want a drink or they can help you . I asked the person that cleaned my room if he could get me a opener for the beer I had bought he told me no I had to call room service, so I did and when she came she wanted to open 1 bottle at a time she wouldn't leave the opener. How can you sell beer with nothing to open it . Now let me tell you about my bar cash. Again, I only purchased 200 because I know I am not a big drinker but I like to have 1 or 2 fruity drinks a day . Well , every few days my debit card linked to my room would have to be re- swiped and they would put a hold on my bar cash . I had no idea until I would go to order and drink and then be humiliated in front of all the other guest. I had to go to Guest services several times regarding this. I was so fed up I asked the desk person to refund my bar cash I was told that only you can do that. I was actually in tears I felt so un appreciated I don't think I will ever go back . The food was cold most of the time . I ate brunch twice , once it was good and one time my husband ordered a bloody maria and they never brought it . I feel the ship is not staffed well and could use some serious customer service lessons . This brand new ship has a horrible smell too !! Smelled like dirty diapers. I will not said Carnival ever again. I also called them and sent a copy of this letter and not one phone call or email did I receive .
