Grandma has a hot tub, and when the temp is lowered it's very much like a warm pool! The first week we were in CA the weather was very warm (in the mid 80s) which made the hot tub perfect. The second week it was much cooler and the idea of wearing bathing suits, even in a warm tub did not appeal. We did however get the girls and grandma in the hot tub the day before we left to come home. The girls had such a great time! It was Eleanor's first time in a "pool" and she seemed to really like it and she looked seriously adorable in her kitty cat bathing suit!
