Just wanted to say HI! I too am from Chicago and planning a June 2012 wedding. :-) we are getting marred on June 29th in the Dominican Republic.
What I would suggest is get in touch with a travel agent. There are some that offer services for free. The company I went with is Free. The Travel Agent can help get you information on different resorts/hotels in the area of your choice as well as pricing. Might be helpful.
