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 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). In years past, we’ve toured a distillery and sampled fine whiskey, 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.

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.


Do you have a special area of expertise or something you’re passionate about that you wish to share with your fellow Mensans? WeeM is the perfect opportunity to do so. Simply fill out the Speaker Form and our Program Chair will get back to you. If you have any questions about being a presenter, just e‑mail our Chair../images/email-regular.s.gif.

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.

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 — double entries for wee hours. They are adored by WeeM ghosts and goblins, and are protected from evil spells, light sabers, Vogons, etc. So why not plan to volunteer for a few hours and then contact us this fall!

Help The Economy!

Check out 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.
