Hi, I believe there was a thread not too long ago about this, but seeing as the search function is disabled....
I have been to the Sagamore a few times, (we live in upstate NY about 45 min from there). The summer is a beautiful time of the year to visit, there are lots of fairs going on, Saratoga Springs is a great place to take a day trip and go to the track too if you are going before season close, there are a number of great restaurants in SS as well. Lake George is only a short drive from the Sagamore....there are lots of boating, miniature golf, fishing, swimming, etc opportunities in the summer. We've heard that the dinner cruise from the village all the way up to Ft. Ticonderoga and back is really nice, but we have not taken it yet, just done the 2-3 hour ferry trips. The rooms at the Sagamore were very nice, the 'porch' area looking out on hte lake was great too. We did not eat at any of the restaurants at the hotel, but did do the breakfast which was VERY good!
Anyways, have fun planning your trip!
