My mother and I were talking about a possible trip to see Universal all decorated for the Holidays. Also what are any must do's for that time of the year. It feels odd to be talking about Christmas when it's almost 100 out.
I asked a CM this exact question last week (as I'm planning a trip also). She said for sure the Wednesday after Thanksgiving. November 30 this year? They are quite impressive to see.
You'll love Christmas at universal the decorations are great...i love the trees in suess landing. make sure you take the time to see Grinchmas, its great and hopefully while you're there you can watch one of the Christmas concerts.
