First Time at a Disney Resort

[AP18]

Hello my husband and I are staying on site for our trip in November. We are staying at CBR from Nov 28 to Dec 7th. I am looking for any tips you have for first time resort guests, we have the free dining plan and we were thinking of attending mickey's very merry Christmas party. Is the party worth it?

Any tips are welcomed for the resort and party. Thanks in advance!
