Nevermind...found out how much it was. A little too much for a mini Christmas tree for two nights for us. lol. We'll just enjoy the one in the lobby and ours at home. lol.
There are also cute little trees for sale in some of the shops. I bought them in the Christmas store in DTD and also that general WDW merchandise store on the left as you enter MGM/DHS. They're just $30. Batteries are included.
