HalloweeM 4D: Time Travel

October 29 – November 1, 2015

  • Join us for four days of RG fun where the cool smart 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
  • A huge game room and tournament offerings including Poker and Werewolf
  • Annual favorites like the pun-tastic Friday night costume contest and Saturday night Pretentious & Prohibition Drinking
  • Two dances
  • And … an excellent hotel!

Travel through another dimension and join us at WeeM! There’s no RG like this! Stimulate both your mind and senses.

Nothing, that's what! Enjoy rousing debates and thought-proving points of view at the 40th HalloweeM! Early bird registration is open, so register now to get the very best rates. We've also secured an amazingly low hotel rate for this year of $115 a night, so long as you book by July 27th. So, in the Chicago way, book early and often! Rooms will fill up fast at these new lower 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.

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 brewing in our great caldron or join our WeeM-Notify mailing listNew Tab to get email updates (no more than one a month, except in October).


Excursions will be planned for Thursday (no one wants to miss the fun at the hotel on Friday). In years past, we’ve visited Devon’s Desi corridor, created stained glass works-of-art, shot guns, blown glass, visted the Regional Crime Lab, 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.

The Best Place 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/open_new.s.png 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.

Are You Naughty or Nice? The Best Flakes …

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. They are adored by WeeM ghosts and goblins, and are protected from evil spells. So why not plan to volunteer for a few hours and then contact us this fall!
