We are just coming home today. I will preface this with the fact that we live in Texas, so we left 85 F temps (30C). We had been visiting our DD in Berlin, where it was cold for us (40’s F) but sunny. DLP was highs in the low 40’s F and misting/raining the entire time we were there. For us it was long underwear, coats, hats, scarfs, gloves weather! We are generally rope drop to park close people at the US parks, but at DLP, I was very happy we were staying at the Marvel hotel so we could go back to the room for a mid day break and warm up, change wet socks and shoes etc. I wished we had waterproof winter boots for this part of the trip, but we did carry on only for 9 days, so that was not possible. I think that would have helped us though!
I am sure the weather can vary a lot in November in DLP, but be prepared for cold temps and pack layers accordingly. We saw many, many people buying coats/hats/gloves in the parks because they didn’t pack warm enough clothing. We usually like to wear Disney themed shirts to the US parks, but we didn’t have room to bring them on this trip, and I thought they would just be hidden under our coats. Boy, was that accurate!!
Have a great trip and happy birthday!
