If your going to WDW to experience the holidays, isn't this event why your here?
Pros:
- Characters you don't normally see and they come out in large groups (7 dwarves + snow white all together for example).
- hot chocolate and cookies (not all that exciting but does add to the mood).
- park has different holiday background music
- main street is a little bit different lighting (halloween is very different).
- snoap on main street (fake snow falling down).
- xmas parade
- different fireworks that are 360 around the kingdom in a couple spots.
- holiday stage shows (castle stage and tomorrowland stage).
- there is a lot of dates and not going means out of the park by 7pm on those days
- if interested there is a themed desert party you can pay even more for (not worth it in my opinion and if your running around for characters, it'll take away time from that).
- see first con on crowds but if it's a non-ride crowd, rides are quick to get on..
Cons:
- might be crowded. crowds are either doing rides or everything but rides. it could go either way on any night for what you want to do while there.
- later at night, if your not a close the park person it could be a stretch to stay up and may impact your early morning get up and go somewhere plans.
- the day crowd might actually be smaller then the party crowd since everyone sees close at 7 and do another park.
If you skip con:
- the other parks will be more crowded at night because mk isn't opened for them.
You can wait until like December 20 or so and watch the party parade for free during the daytime at MK
There is a party on dec 22, it's probably going to be only 2 or 3 days it'll run without the party..
