Need some recommendations. I'm starting the site selection for a group who would like to go to the Northeast in August 2015 for a conference (over a weekend). Basic needs: high-end property (4-5 stars), 10K+ sq ft ballroom, at least 500 sleeping rooms, golf course, family friendly, traveler-friendly location. We originally wanted Boston but all hotels are either too small or not available. This group loves the outdoors so location has to be ok in the August heat. Thanks for your assistance.
