Hi Greg:
The Ponce Hilton is located in Ponce, PR. They also have a $5 chip. Sorry I don't have extras left. Ponce is located on the south side of the island. The POnce Hilton is somewhat out of the way. I believe that is opened around March or April, 1997. I found it by accident while I was touring last year.

Sorry I can't help with the other 2.

Regards,

Mike
