Chicago Area Mensa Presents . . .


October 31 – November 3, 2019

Check this site in the spring for information about our 44th WeeM!

  • Join us for four days of RG fun where the cool smart people party — including everything you expect from WeeM ... and even more!
  • Multiple tracks of programs to keep you intellectually stimulated
  • An RG on the grandest scale, with over 500 attendees
  • Lavish and plentiful hospitality with lots of room to socialize & chill
  • Huge game room and tournament offerings
  • Thursday Off-Site Excursions
  • Annual favorites like the pun-tastic Friday night costume contest and Saturday night Pretentious Drinking & Epicurean Experience events
  • Dance (usually Friday and Saturday night)
  • And … an excellent hotel!

Join us at WeeM! There’s no RG like this! Stimulate both your mind and senses.

Come to WeeM to have fun with over 500 fellow Mensans and their guests. Play games, attend seminars, dance, talk, eat, drink, volunteer, and laugh. Check out the photos to see what happened in past years. Once you come to WeeM, you'll be under its magical spell, returning every year. WeeM is so special, you'll want to make the trip — some cross the ocean just to be here!

Enjoy rousing debates and thought-proving points of view at the 44th HalloweeM!

The links at the left, and throughout this page, will take you to general information about HalloweeM and specific information (as it becomes available) about this year's gathering – WeeM registration, hotel reservations, programs, and much more. Return often to see what's new or join our WeeM-Notify mailing list to get e‑mail updates (no more than one a month, except in October).


Excursions are planned for Thursday afternoon (no one wants to miss the fun at the hotel on Friday when they used to occur). Our coördinator can also provide you with information for a self-guided walking tour if you wish to venture into the city. Our Excursions page includes places you can explore on your own as well.

Our Hotel

We continue to be excited about the venue. The Westin Chicago North Shore Hotel in Wheeling has a lot to offer. It hosts other events we know of with comparable size and similar people, and we have worked with some of their senior staff as well as the people behind the scenes who do an amazing job helping us volunteers to keep things running smoothly.

Too Much TV is Bad for the Children So …

Bring the kids! Chicago has been working with several dedicated volunteers to create a kids' track at our functions. We've ironed out the details during our Monthly Business Meetings during the year and are pleased to offer you and your kids a wide variety of activities throughout the WeeM weekend. Babysitting will be offered during certain events, and WeeM speakers will deliver programs tailored for the kids.

Fun, Educational, Intriguing

A plethora of programs is being offered, as in in years past. This year you can expect to see some repeats of popular programs and new ones as well. As usual, you will not be disappointed, other than trying to decide which program you'd prefer to see and which ones you'll have to miss because there are too many great ones going on at the same time.

The Stars of Our Show Are Our Volunteers … Why Not Join the Cast?

You may not see them, but you see what they do. Volunteers are the caretakers of our amazing, four-day event! They earn collectible WeeM pins and entries into the Volunteers' Raffle — double entries for wee hours. They are adored by WeeM ghosts and goblins, and are protected from evil spells, bad casting directors, etc. So why not plan to volunteer for a few hours and then contact us this fall!

Get Some Bling & Help The Economy!

Check out our annual book sale to benefit Curt’s Café, which improves outcomes for young adults living in at-risk situations through work- and life-skills training. Bring your own books that are just taking up room and collecting dust, and allow us to sell them for this charitable cause.
