I have not been there this year but just in case this slipped by people, last year the Diamond Club tickets had $35 food and bev loaded on the tickets. This year, it's all the food and draft beer and wine you can handle, I believe.
Service at the seats is def dependant on the attendance. If it's a full house like on OD, they just can't keep up. I suspect it's much more difficult this year given the free food and drinks.
I use my Red Carpet Reward points to upgrade to a Diamond Club a couple of times a year.
