I have been doing research online through Yelp and The Knot but am  feeling overwhelmed and don't know where to start.  I am getting married  October 2015 and am starting to research sites for a wedding.  We are  going to probably invite anywhere between 120-150 guests and have a  budget of $70-$90/guest.  The ideal location will allow us to do a  ceremony and reception onsite but is not necessary.  Also, having an  onsite planner would be a major plus.  The place must also have parking  and be in the northern suburbs (Glenview/Northbrook, Lincolnwood, Niles,  Des Plaines, Rosemont) or north side of the city.
I have looked  at and will probably visit the following: Glenview Park District,  Chateau Ritz, Maggianos, various hotels in Rosemont.  It is tough to  find reviews and very few reviews are recent and do not give a good  flavor.  Any suggestions on places to look or anyplace to avoid?  I am sitting at work almost in tears because I am getting so anxious/overwhelmed.  Any guidance would be helpful.
Thanks!
