Yeah no costumes on adults. If you do wear a costume, especially anything that resembles the Tron movie costumes, it is under your discretion because if the the main gate security sees you in costume, they will get on your butt about it, trust me, it happened to me and caused big problems wearing my Quorra costume there one time, this was after Halloween, during October I wore it twice and had no problems.
The thing is I was with a couple of friends that were done up head to toe, obvious they were dressed for ElecTRONica ready to party. Well, it caused too much attention plus, I was holding my disc in my hand, they saw that and told me no Tron costumes can come in here.
So word of the wise, please if you are going to attempt to wear any light up Tron costumes, wear a long coat, cover up entirely. Carry your makeup in and finish your look in the bathroom. Do not make yourself obvious or they will not let you in.
Other than this report....... HELLZ YEAH!!!!! ElecTRONica to the end... OF LINE! Keep it going Disney, best idea you have had yet!
