It's well worth it -- unless you happen to be at MK the week of Christmas.
There are special pins that can only be purchased (two of one style per ticketed guest) on each night of the parties.
Each MVMCP (&
MNSSHP) offer a special pin to be purchased for that night only.
Guests can buy whatever pins may still be available from previous evenings.
And only hard ticketed party guests can buy these pins. The pins are usually limited to 2,000.
After all the parties are done, whatever pins are remaining regular guests can buy. Some are always sold out.
Even for non pin collectors, they make nice momentos.
That evening's pin can be bought at the Emporium and a few other locations in MK. (The CM will mark your party ticket and your wristband at the time of purchase.)
Any previous party pins have been sold at Expo Hall.
I don't know if these locations will change this year or not.
