Good morning, all:

I may be meeting a date in Manhattan later this week, and things might get a little steamy.  Neither she nor I have a residence in the City, so I'm hoping to find a hotel where I can take her for a few hours while things run their course.  Can anyone suggest a hotel that offers reasonable hourly rates that is clean and a good place to take a girl for about three hours for some fun?

I used to work in the City about three years ago, and I know there was a hotel around 19th Street and Lexington whose name started with a D that offered this exactly, but I can't remember its name and I don't even know if it's still there.  

Any suggestions that anyone can offer would be greatly appreciated.  Thanks in advance!
