BEWARE - This is NOT a 4 star hotel!!!!
As I write this I am still sitting in the Doubletree Hilton - Times Square South, unable to cancel or find other arrangements due to a "prepaid" special I utilized through Hotels.com. 
First of all, this is NOT a 4 start hotel - and believe me, I read all the reviews ahead of time and checked the website prior to booking my non-refundable two night stay for a Thanksgiving trip with family.
Here are a few highlights:
-the hotel has NO bellboy or greeting personnel out front; this includes for arriving guests, as well as guests wishing assistance in hailing a taxi or unloading their luggage from the car;
-the front lobby is so bare bones you'll have trouble finding the check-in desk;
-once we were assigned a room we were shocked to learn that the hotel bathrooms do NOT feature a bathtub! A four star hotel with no bathtub is unheard of, never mind the fact that families with small children will have immense difficulty bathing/showering them!
-the rooms are MINISCULE, and our "two double beds" for a family of 4 ended up being two FULL size beds, with one bed shoved up so close to the wall and the heater unit that my husband kept having to step on/over me during the night because there was only one side from which he could get out of bed!
-the elevators are GHASTLY slow; most guests wait about 10-15 minutes and then surrender to the stairs; this happened multiple times during our two night stay;
-the room was less than clean; the carpets are severely worn and to boot, the cleaning crew leaves the cleaning cart and the vacuum cleaner out in the hallway day and night; evidently they there is not even a closet in which to store cleaning supplies;
-last, but not least, the bathroom door is spring-loaded so that it never stays open; you can't' have a conversation or have a child come in and out of the bathroom without the door slamming on them.
All in all a HUGE disappointment and a MAJOR case of false advertising. This hotel might be 2.5 - 3.0 stars, but it's definitely not 4 and definitely does not merit the $300+ price tag per night.
And of course, it's NOWHERE near Times Square. We found that out the hard way and one $10, 1.8 mile taxi ride later. Ugh.....
