Hi there! We were on the same itinerary as you - July 31st out of Galveston. I'm sorry you were disappointed in your cruise! 😞
To offer a different perspective, we LOVED our cruise! No, we didn't stay up late and do any bars, casinos or the late night comedy show, so it sounds like we did different parts of the ship. But, we LOVED the sports square (we have young children), the pools, the CD was AWESOME, the Atrium events with the CD, the MDR (we loved almost everything we ordered) and thought the shows and comedy we did see were just average. We loved Alchemy, the Ocean Plaza bands, the Lanai seating with hot tubs, the Pub and the coffee shop.
We also agree that the staff wasn't very friendly as compared to past ships. We had a different server each night due to My Time Dining, but service seemed more prompt than our last summer Carnival cruise. Our cabin steward was very friendly and attentive.
Lines were LONG - it was a full capacity ship. But there was always room at the shows and we never waited long for any MDR meal (breakfast or dinner). I think most people were at the buffet, which does serve some of the MDR dinner food.
Pizza was open starting at 9am (and of course we were up then :)) I saw on the schedule the late night buffet was happening, but we were of course asleep by then. 🙂
I bought the CHEERS package. I think I about broke even with alcoholic drinks, but ordered many non-alcoholic drinks as well. It allowed me to try lots of different things and not drink what I didn't like.
Some members of our party did notice aging on the ship, but that didn't affect our enjoyment.
Excursions - in Cozumel we did the Zipline, snorkel and beach excursion through Carnival to Island Beach Club. We loved it (mostly) and would recommend that beach club again!! Other family members did the Secret River cenote swim excursion and LOVED it. They had older kiddos than ours.
Again, I'm sorry you were disappointed in your cruise but I hope the additional review added on here helps others reading to know you can be on the same ship and have 2 very different experiences and desire very different things.
Happy cruising!
