Perfect Base for an NYC Visit
We got to the Doubletree several hours before check-in time, and expected to leave our luggage and head out to see the city while we waited for our room to be ready. When we inquired about the luggage closet at the front desk, we were immediately given cookies and checked in by the nicest front desk clerk I have ever experienced, even outside NYC. 
The rooms are large for any hotel, and particularly large for New York City. As it is in the middle of Times Square (and NYC), it is definitely not the place for a relaxing and quiet sleep. It is, however, much more quiet and sedate than we expected. 
Our room was also clean, free of mold (something we've dealt with in even the most upscale of hotel rooms in other NYC visits), full of towels, and had a pleasant amount of light through two windows. We could see Times Square from our window, and my children spent a lot of time sighing over the huge UFC poster that was nearly directly across from us.
A few tips: 
* If you choose this hotel, you're choosing to stay in Times Square. There is pretty much no difference between day and night, light-wise. Use the blackout curtains helpfully attached to the window or don't complain. 
*The buffet breakfast is mentioned both on their site, in several reviews, and on Expedia. It is not free unless you buy the package that includes it. As of our visit, the cost was nearly $30 per adult. You may not flinch at paying this, but there's a delicious deli just across 47th street, less than 50 steps from the front door. We fed our family of five a delicious and filling hot breakfast for less than $25 and used the left-over money for a museum visit.
*The front door to the room has a rather large gap in the bottom. You will hear every single thing that goes on in the hallway. Some of those things can't be unheard. I pushed a towel up against the door, and it was fine. 
*I hate the revolving door entrance. My children loved it. I used the regular doors, even though they said, "Please use revolving door." The doormen were super nice about everything, even though I was flagrantly disobeying the door request. 
By far the best part of the Doubletree Times Square is the staff. The general manager needs to be heartily congratulated at creating a team that puts the customer first, emphasizes positive attitudes, and goes out of their way to be helpful and add the little touches that make a traveler a dedicated Doubletree client for all business and pleasure travel. 
Oh - and whomever chose the toothbrushes at the front desk is a genius. They clean my teeth better than the fancy brushes I buy at Target.
