Hi just back. We were there from the 3-11. Watch the forcast every night or am before leaving for the parks. I dressed depending on what the temp. was that am, not based on the high for the day. Many days forcasted temp in the high 60's but when you left for the parks it was only 40-44 degrees. On those days you needed fleece hats or ear warmers, gloves, jeans, sweater, or long sleeved shirts and jackets. We did not take winter coats, but warm turtlenecks and fleece or sweatshirt lined jackets. On Days where the am was in the 60's but high's were expected to reach 70's I would wear t-shirts with a sweat shirt or a light jacket on top, and shorts or capris. I found it helpful to always have my fleece gloves and ear warmer in my jacket or sweatshirt pockets. So, I could always access them. One day I didn't plan accordingly and I had on capri's with a short sleave shirt and a sweat shirt on and it rained. So, if all else fails those plastic poncho's they sell in the parks are actually a good insulator.
