We went one year and it was cold! I am talking colder than Massachusetts where we are from. It was a big family joke for a long time. We were fine because we had our winter jackets/hats/gloves but some people were freezing. Stores were packed with people because they had heat, people were using towels under ball caps to cover their ears/keep their heads warm, people were putting socks on their hands for gloves....It was quite a sight. No, I am not saying this is the norm and honestly we had a lovely time but just pointing out what can happen. Layers are soo key that time of year!!
