Spa Recommendations for Queens, Nassau or Manhattan?

Anyone have any spa recommendations for Queens, Nassau or Manhattan?

I want to go to one for my bachelorette party.

Thanks!

Try Chelsea Piers. They have a huge spa, and then you can probably use other areas of the facility for fun stuff.

You could really make a day out of it.

Here is the Chelsea Piers website:

If it is a nice day, you can walk along the water. There is a beautiful park nearby where you could even do a picnic lunch.

In the city, I'm a big fan of the bliss spas and Townhouse Spa (55th I think).
Also check out Sparty. They host spa parties in their locations or yours. It's $$$ but very cool.
