Yes, I have! :0

Newark Gateway Hilton- It's a miss for sure!

Hilton Short Hills- Literally one of the best of all the Hilton US properties.

Yet these are not in Manhattan/NYC by any stretch of the imagination and so I'd try the Millenium Hilton which often has outstanding weekend bargain rates as has been noted!

Best of luck and if I can help, please just ask! Have a great weekend- and when you visit too!
