I'm a Marriott man...

And the above post mentioning the Courtyards and Marriott Suites and Lincolnshire Resort is on the money...they are all nice properties.

There are actually two Courtyards on Lake-Cook Road, a few miles apart...the closer one already mentioned is in Deerfield, the other one is in Highland Park. Both were built in the 80's and are first or second generation properties, meaning, they actually have a nice, landscaped courtyard in the middle, unlike newer Courtyards which don't have a courtyard...lame. Both have been renovated several times over the years. Source: I worked at most of the Courtyards in the North Shore and several of the Residence Inns.

There is also a Wyndham Garden on Lake-Cook a few miles in the opposite direction in Buffalo Grove... price point is way better, but this place seems kind of mediocre, from what I have read. If all you want is a clean place to sleep that's not a dive or budget hotel, it should be fine. It's about a 5 minute drive from the Westin, in light traffic.
