HalloweeM 45: The Unreal WeeM

October 30 – November 1, 2020

Illinois Phase 4 restrictions limit group sizes to 50 people, so sadly our in-person HalloweeM is postponed until 2021.
You can, however, participate in the virtual Costume Parade, among other offerings TBA.

Come to WeeM and Register at the Door!

Bring your Mensa number to registration and pay by check or cash.

A photo id will be required for any adult picking up their Pretentious Drinking coupon for Saturday night. You will not be able to get them for other adults in your party.

Registration Rates

Please note that Mensan rates assume membership in good standing. IDs will be verified on-site when you pick up your badge. The additional charge for non-Mensans or Mensans whose membership has lapsed is $10. For anyone paying this additional charge, membership forms and/or coupons for a discount on testing will be available on-site at the registration desk.

There is no charge for children age 8 and under to attend when accompanied by a registered adult; and there is a discount for attendees under 21 years of age.

If you preregistered and were paying by check, it must have been received by the appropriated deadline to qualify for a discounted rate. Otherwise you will be expected to pay any additional amount when you pick up your registration materials at WeeM.

Full (4-day) Registration

This is your best value, particularly if you register early! Enjoy four days of programming, hospitality, and fun activities hosted by Chicago Area Mensa!
