My sis has stayed on concierge floors in multiple resorts at Disney and actually throughout the real world. Being my sis, I've had a couple of WDW experiences with their concierge level with the bonus of not having to pay for it. I've only stayed myself at the concierge at the Portofino at Universal. Nice! You do need a larger tip allowance in your budget though.
From what I've seen it is a waste if you are open to close, plow through the parks. You miss everything the club level offers. Now if you tour the parks the way you did in your last trip report, it might be nice for your anniversary. Note, the concierge really is not a help with dining ressies that you can't do on your own. They are not like the dudes at the Ritz with connections.
There is always coffee, juices in the morning. Real coffee! Plus the one cup stuff. A decent spread of the usual stuff set out for a quick breakfast. Would be good enough for me and I could then spend my dining credits for dinner and lunch.
The common club room is OK, depends on who is in there with you. A few comfy couches and chairs, kids and adult TV. A few times I was up there you'd think it was a playground for how parents let their kids run off steam in that room. Other times, nobody. Kinda cool to look down at busy lobby and have a peaceful break from the hustle and yet quietly observe.
Now if you come back for a break in the afternoon there are hoursdouvres. The hot ones I had were good or OK, not over the top,
hit the spot and held us all over until a later dinner. They had several wines and beers. Wine choices great for me, hubby and BIL, more fussy about beers. Cheese was yummy.
At night Sis said they did the typical turn down, turn on a light, chocolate of course. Fridge did have some of the lounge staples of coke, water etc. The Fridge was a bigger deal before they were standard in most WDW rooms.
Basically if you have the extra money for the splurge and tour like you did on your last visit, you'll likely enjoy the special treat.
Some people are like Slinkies.
They aren't really good for anything,
but they still bring a smile to my face when I push them down a flight of stairs.
Friends are Gods way of apologizing to us for our families.
