The first thing I see as I travel around to several different forums and from emails from friends? The NH Carlton is in play. More so than the NH Amsterdam Centre.....at least right now with recent bids.
And for the summer months ahead it looks like the price point is somewhere around $62 or $63 USD for the lowest winning bid.
July 22-26 $65 first bid. Carlton
July 8-10 $63. First try at $61 failed. Carlton
August 11-13 $69 which was a counter offer. Carlton
July 21-27 $63 first bid Carlton
There may be other 4's in play. But if so they are not being posted.
