We are planning 4 days at the parks, it will be during the busiest time of year (the week after christmas). We want to celebrate my oldest daughters 5th birthday and she is a christmas eve baby so no way avoiding the crowds. It will also be me my husband and our youngest daughter who will be a month shy of 3. My question is since it will be so busy should we do 2 days at magic kingdom and eliminate animal kingdom or do all the parks and just do as much as we can at each one. I appreciate any advice I can get.
