I have done both and enjoyed both, but I did
MVMCP just once and
MNSSHP every year for 5 years, sometimes twice in one week.
Christmas is a wonderful time to be at Mk and the decorations are marvelous, love the "snow" on Main street and the parade. The weather is ncos during the day and sometimes brisk at night
But Halloween is great. The parade is one of the best and I love the villains! Seeing the characters in costume (Pooh bear as a honeybee is so cute!), the opportunity for villain meet and greets and Hallowishes fireworks are not to be missed. The weather is usually still hot and muggy so if you go in costume, pick wisely.
