The thing about club level is that you have to be in the resort to use it. Unlike your club level at DL, getting around WDW can be time consuming, and you say you are light eaters. I have never been able to run the numbers in a way that has me thinking CL would work for us because although we are "resort" people who love time at our resort, I just can't see us getting our money's worth and I don't like to be tied to anything that ties me to one park, or restaurant to get what I paid for.
I love OKW but do have to say, given the age of your kids and it being their first choice, I'd save that for another trip. When they are older and into the whole DTD thing and you need the extra space of a one bedroom then OKW and your own DVC contract will be the way to go.
I would go with WL if that theme appeals to you but not do the CL.
And all this said, I would seriously look at the moderates. We have stayed around the World so to speak and the moderate levels work for us even better than our DVC stays back when we were DVC members.
Any of the mods is great, although I find the one and only pool at POFQ too small and the slide is lackluster.
POR, CBR and CSR all have a lot to offer, great pools and activties. So I would think about one of those or stick with WL.
Regardless of what you do, your kids will have a great time at WDW, its poor mom who in the midst of all the planning and choices that gets stressed beforehand!
