Just got back Thurs. from 5 night trip solo!!! Weather was perfect - up to 80's but with cool breeze during the day, down to low 60's high 50's at night and early mornings. Supposed to rain one day, but only did for about half hour late in the day. Stayed at POP. Seemed quite busy everywhere I went, but extra magic hours were great for walk-on rides, especially the morning ones, and fastpasses helped when it was busy later in the day.
One thing travelling this time of year - everyone seemed to have a cold or cough. I myself got a bronchial infection and ended up spending $20 on medicine to help calm my coughing until I could get home to my doctor yesterday. And everyone on my flight was coughing and sniffing on the way home. So just be prepared for any kinds of illness travelling in the winter months, and take lots of medication with you because it costs twice as much at the gift shops.
