GN 24Karat Players Club in AC

Finally got around to doing an overnight trip staying at the GN.
In about 4 hours of playing my usual games, I picked up 1,000 tier credits.
That same play at Harrahs usually gets about 400 tier credits.

The room was comped and actually pretty nice.
The H2O bar by the pool was very nice.

The Borgata is one stop on the number 2 jitney.

I liked the 10 am poker tournament, and will probably play there again.

Question: is the 24 k club worth devoting playing time to.
5,000 tier credits in six months gets the black label "chairmans club"
They measure your play Jan 1 to 6/30, and July 1 to Dec 31.

I will also do at least one downtown LV trip this year. Does the black card earned in AC get you anything in LV.

Curious to hear what others think.
Hey Now!
I asked in Feb, and was told the properties weren't linked yet..
