Am I being ungrateful?

So, in 2022, my dad and I planned that our big family vacation in 2024 would be to Canada. We would go skiing and stay in a snow lodge. However, he changed things last minute to a cruise, which really upset me. We went on a cruise last year, and I absolutely couldn't stand it. I'm on the spectrum and have issues with bipolar disorder. There were way too many people on that boat, it was extremely hot, and I had about three panic attacks. It was also boring, and I couldn't find anyone in my age group. I got overstimulated, and while the food was okay, overall, it was a terrible experience for me.

Now, my dad has booked another cruise, and I told him that I was overstimulated during the previous one, and we had already made plans for Canada. He responded by saying that he thought I wanted to go on another cruise. I explained to him that I wouldn't enjoy this one either. He argues that I'm older this time. However, I want to point out that when I went on the cruise last year, I was 19, and this year I'll only be 20, so there won't be a significant difference. Now my parents are calling me ungrateful, but I don't understand why, given that in 2022, he asked me what I wanted to do.
