hi we're going to orlando 20/12 for 2 weeks spending first ever holiday away from home at Christmas. Its a special holiday planned for my 14 year old son who has recovered from cancer for the second time in his life! This time bone tumour in leg. I'm worried about what I've read regarding the crowds and admissions to theme parks. We've booked Christmas lunch at Liberty palace but what if we can't get in to MK on Christmas Day? Also any suggestions would help as son can walk but may get tired.
