WE did our first Disney on Ice last winter and the girls were almost 3 and 4 1/2 and they both loved it. We had done a regular Disney show the year before and again, both girls loved it.
We went when DD was 3 and she loved it, and funny enough my DH and I enjoyed it as well. I plan to take her again next year and any other Disney shows that come our way.
My mom took DS1 when he was 3 1/2. He loved it! He still talks about it still likes to look at the magazine/souvenier they give out. He wants to go again.
We are taking the kids in March to the Treasure Trove show. My DD turned 3 in december and she is really excited. We aren't sure how much DS will care, he'll be almost 2 when we go. If he wasn't free, he wouldn't be going becuase I'm almost positive he is not going to sit and watch.
Re: what age for Disney on Ice?
we did dare to dream at 3.5yr
I wouldn't have done it any younger. for my kid at least
