We went last Feb. and are going again this year. My daughter was 10 months old on our last trip. We found it to be damp and a little foggy when we arrived at the parks at opening. We found it easy to put her in a cotton jersey type short sleeve dress with a thin pair of cotton jersey type pants under it and we would need a sweatshirt jacket on too. As the fog burned off, it would get warm and we would start by taking off her jacket and then as it got even warmer, we would slip her pants off and put on a pair of bloomers under her dress. We plan to do something similar this time around too.
