Looking to book for one night in July. Ideally somewhere on Manhattan. I have a free reward night so looking to make the most of this, although would like somewhere that will ever allow late check outs or that will store our luggage for the day. At the moment my choices seem to be: Wingate by Wyndham Manhattan Midtown; The New Yorker; Wyndham Garden Chinatown.

Also, what are the rules regarding booking a 'go free' stay with regards cancellation?
