I'll chime in here since I just did this trip - although I did start at Bethpage.
The Links at Unionvale - I thought it played very fairly with many interesting holes - generous landing areas and true greens with movement. Excellent condition.
Hiawatha Landing and Conklin - With all due respect to Mr. Flemma, a little of a letdown here. Hiawatha is quite narrow and condition a little under par. I just didn't fine it all that interesting after Unionvale.
EVERYONE on this trip said I must play Conklin - so, I gave up Mark Twain for a round at Conklin. If you like mountain golf - as in a course laid into the side of a mountain, you will love Conklin. Excellent shape - great views and very pretty. But, it is up and down the mountain - as is Morgan Hill in PA.
While in Binghamton, you may enjoy En-Joie where they play the Dick's Sporting Goods tour stop - I walked it after Conklin, and enjoyed the big trees and long shadows late into the evening - fine shape after the recent tournament. Good muni.
Architects was a treat - with each hole modeled after the style of the great GCAs, it was fun to play and experience. Wide open in rolling terrain and plenty of big bunkering and greens with lots of movement.
That's my take on it - have fun and let's hear what you choose and how it goes.
