Ghostbuster cosplay

[Eric McKenzie]

Hello everyone, so my girlfriend and I will be coming to Mickey's Halloween party in October. Now I wanted to dress as Dr. Egon Spengler from the Ghostbusters movies. I have the entire suit and gizmos but most importantly I have a proton pack. Now that also is where I am concerned, will I be turned away because of my proton pack, it is a movie replica not the blow up ones seen here and there.

If anyone can help or verify please do, thanks in advance
