Just my opinion, but it's not worth it to us (DH and myself) to pay $100 a night for club level.
We have been fortunate enough to receive free upgrades to club level twice, so we have been able to experience it. Don't get me wrong, we did enjoy it, just can't justify spending my own money doing it. Depends on your personal finances. I can really pinch a penny when I need to, and I am an annoyingly logical thinker, so for $100 extra a night for our usual 4 night stays, that $100 a night could pay for an extra night's stay.
We have enjoyed the food offerings, but since we drive to WDW, we can bring our own wine and snacks for a lot less money. I have never asked any of the CM's for any additional services. Can't imagine what they could do for me that I can't do for myself. Again, just my opinion.
We hope to spend our 30th wedding anniversary at Disney in April 2016, but doubt it will be at club level, unless we win the lottery, but that's just us.
