  • An RG on the grandest scale, with over 500 attendees
  • A wonderful and lavish cantina experience with lots of room to socialize!

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! Registration is open, so register now to get the very best rates. We've also secured a great low hotel rate for this year of $117 a night, so long as you book by October 17th. So, in the Chicago way, book early and often! Rooms will fill up fast at these rates!

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 e-mail list to get e‑mail updates (no more than one a month, except in October) — you must be on the WeeM-Notify e-mail list in order to receive the “M-Letter” but it will be posted here on the website in late October.


Excursions are planned for Thursday afternoon (no one wants to miss the fun at the hotel on Friday when they used to occur). Take a Tour of Chicago Executive Airport or enjoy a History Tour at The Grove. More excursions may be added. Sign up now! 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 and some dining recommendations as well. Sign up soon or there may not be any spots left. The deadline is October 25th, but may close earlier depending upon demand.

Book a Room Now.

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. The hotel room block is set up and ready for your reservations. Problems with reservations may be forwarded to The Hotel Liaison../images/email-regular.s.gif for timely resolution.

Too Much TV is Bad for Young Padawans So …

Bring your young Padawans! Chicago has been working with several dedicated volunteers to create a special track just for them at our functions. We are pleased to offer you and your kids a wide variety of activities throughout the WeeM weekend. Babysitting. will be offered during most of the weekend, and WeeM speakers will deliver a number of programs tailored for a younger audience.

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 Force is Strong with Our Volunteers … How About You?

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 volunteer now? Peruse the PAAG to figure out which programs you’d want to attend when figuring out your volunteer schedule.

Attention Vendors!
Our Vendor Coördinator is still accepting applications for space at WeeM. Refer to our Vendor Flyer for all the details. PayPal is required to submit your payment. The deadline is October 20th.

Get Some Bling & Help The Economy!
