Hi Norma and welcome to the Disney Parks Moms Panel.
That is a tough question to answer as it really depends on which Disney Resort hotel (specifically, or type of hotel; Value, Moderate or Deluxe), you want to stay at during your visit to the Walt Disney World Resort, how many Table Service & Quick-Service meals you intend to have each day, as well as many other factors.
I would suggest pricing a trip up under both
Special Offers and see which one works out to be of more value to your family.
I would highly recommend purchasing tickets to
Mickey's Very Merry Christmas Party if it will be taking place during the dates of your visit. This is one of my family's favourite Special Events to attend and is a lot of fun! I particularly enjoy seeing all of the Disney characters dressed up in their festive attire, watching Holiday Wishes and who could resist seeing it snow on Main Street U.S.A.
Wishing you a magical trip filled with memories which will last a lifetime!
Emma
