We (my husband, two daughters and me!) are planning a December/January trip

and was wondering when the Christmas decorations are removed. We will not be staying on property until Dec 31st.

We will be visiting a few days before, but staying at my Dads home. I thought we would drive to Epcot one day from my Dads however I would also like to see the light show at Disney Hollywood Studios. Perhaps a second trip from Dads.
This is the first trip around the holidays...we are sooo excited! I would like to enjoy as much holiday events as possible.
I love planning far in advance and want to surprise my Dad by taking him to see the holiday festivities...he has never been there at that time either. (He just moved to Florida two years ago).
Thank you for any help!
