Got the flights booked, just need to find a place to stay that won't cost more than my sons' college tuition. Likely going to use Airbnb for housing, and plan on staying in Manhattan and taking the subway over to get to tennis. Planning on grounds pass for the most part, unless wife is uncharacteristically free spendy and wants to try to buy some seats in AA that are out of the nose bleed area. If anyone has any "If I was going to the US Open again I'd do/NOT do x, y, or z again, I'm all ears. Thanks!
