Rainmaker, I hope you who are attending the Chicago show have contacted the company for a complimentary show floor pass. Also, if MMR is holding an after party you should be able to get an invitation. I participated in many security conventions over the years as an exhibitor and what I stated above is common practice. If MMR is not hosting an after party or happy hour then ask them which ones they will attend and then try to get an invitation from that vendor. Great networking opportunity.
If you don't get a complimentary floor pass there are normally free passes at the registration area.
