HalloweeM 42: WeeM, The Universe, and Everything

  • Join us for four days of RG fun where the cool smart people party — including everything you expect from WeeM ... and even more!

  • An RG on the grandest scale, with over 500 attendees
  • Lavish and plentiful hospitality with lots of room to socialize & chill
  • A huge game room and tournament offerings
  • Annual favorites like the pun-tastic Friday night costume contest and Saturday night Pretentious & Prohibition Drinking
  • Dance (often two nights)
  • Off-Site Excursions
  • And … an excellent hotel!

Preregistration is now closed. Come to WeeM and, if you haven't preregistered, please register at the door. If you preregistered but your payment was not received by October 12th, you will have to register at the door and no discounts for which you may have qualified will be honored.

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

Enjoy rousing debates and thought-proving points of view at the 42nd 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 $127 a night, so long as you book by October 20th. So, in the Chicago way, book early and often! Rooms will fill up fast at these rates!

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 There may be no place like home, but WeeM so special, you'll want to make the trip.

The links at the left 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 email 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) with a “Geek Tour” Tour at North Shore Distillery or the opportunity to take an art glass tour, watch a demo and then create your own blown art glass. In years past, we’ve visited the Devon’s Desi corridor and the Northeastern Illinois Regional Crime Laboratory, toured the Nielsen-Massey Vanilla Plant and the Sketchbook Brewery Company, enjoyed a wine and olive oil tasting, taken a walking history tour of the 1800s town of Long Grove, created stained glass works-of-art, shot guns, enjoyed ethnic cooking classes, and visited architectural gems. Our coördinator can also provide you with information for a self-guided walking tour if you wish to venture into the city.

Return of the Masseuses!

Exhausted? Stressed? Worn out from your travels? There will be several massage therapists to do chair massages during WeeM. They will be cash only, $15 for a 15 minute chair massage.

The Best Place in the Universe to End Up! 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.

Won't someone think of the children?

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.

The Best People are 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 &mdash double entries for wee hours. And this year, while the supply lasts, volunteers will get a "Don’t Panic!" towel, so you definitely want to sign up early. They are adored by WeeM ghosts and goblins, and are protected from evil spells, light sabers, Vogons, etc. So why not volunteer now?

Help The Economy!

Check out the Shopping offerings that you can can expect at WeeM, including WeeM logo items you can order now, and our annual book sale to benefit our Gifted Youth program! Bring your own books that are just taking up room and collecting dust, and allow us to sell them for this charitable cause.
