Well your response for interest in a little TLC for ourselves was overwhelming..
So .. it doesn't look like we would all be able to gather in a single spa.
BUT.. I did go onto Groupon Chicago
and there are a bunch of deals (they even have a map to show you location to the hotel)
Get Pampered in Chicago
UPDATE: Looks like this one is nearby the hotel.. facials for $59...
So if you click on this link.. you can see the current groupon.coupon's and if you click on ALL DEALS at the very top of the page, there are even more groupon coupon deals.
So happy hunting.. hope you all find something that will wisk you away (at least for an hour).
