I don't think I ran in the 15's....just the 14's and previous. Also, I am mostly "shoe-oblivious" in these, which means the various versions of Ghosts have worked fine for me, and I doubt I could tell the difference in drop, cushioning or performance if I had to.
And totally get the hotel thing. NYC prices are---I was going to say high, but honestly compared to Disney that would not necessarily be true! I stayed downtown in 23 when I ran--Hotel Indigo on Water St. Partly for cost reasons, partly for tourist reasons and partly cause I could walk to the ferry. And the price was good when I booked.
