I have 2 free nights from the Chase Hyatt card and looking to use it early October.

The Park Hyatt is unavailable (already checked with the GP Concierge on here), as is the Andaz 5th Ave and Hyatt Union Square. I have 3 adults so some places don't have a room that fits more than 2.

Right now I'm booked at the Andaz Wall Street. We don't need to be near Times Square but wouldn't mind it but think we'd be ok with a quiet location. I'd rather be in a "nice" hotel with better service. It seems like the breakfast at the Wall Street isn't great but that's fine with me. How are some of the other Hyatt properties around Manhattan vs the Wall Street one? (excluding the ones that are not available) (i.e. the Times Square location)

I have an early flight out to London on BA from JFK (715AM flight) on a Wed morning but I'm guessing traffic out to JFK at that time shouldn't matter too much whether I'm leaving from Wall Street or Mid-town?
