I was just there (March 5-14) at WKORV. I was in the same situation and decided to cash in 18,000 options for $220 in resort credit. Note that my comments apply to WKORV and WKORVN — right now they are prohibiting WKORV/N guests from utilizing Nanea facilities and vice-versa. My advice would be to call a Nanea concierge and ask what's open and where you can use the credit, my understanding is that you will be limited to whatever is open at Nanea and won't be able to use WKORV/N stuff.
The two of us found it challenging to use $220 on our 9-night stay. The only place the credit was usable was the pool bar at the two resorts and the food-truck-poolside-restaurant (Paniola Grill or something like that) at WKORV-N. At the end of our stay, Auntie's Kitchen reopened with just a few grab-and-go type entrees and we were able to use some of the credits there. You could not redeem the resort credits at the general store off of the lobby, and there is/was no "sit down" type dining open at either resort. So at least during our stay, it was basically drinks at the pool and sort of take-out breakfast or lunch at Paniola's or Auntie's. And we aren't big drinkers, so at the end of our stay we still had something like $70 left.
Ordinarily I think you could also use the credit for spa services (now closed) or at Pelehu (also closed.) If you are big drinkers, it won't be hard to use credit sitting at the pool and drinking Mai Tais, if the weather cooperates, but we had a few days where the pool wasn't really an option because of weather. On the morning of our departure we used up the rest of the credit with a big breakfast at Auntie's and a VERY generous tip charged to the room (figured I'd rather see the rest of the resort credits go to the staff than simply lose it through non-use.)
One other note: since they don't provide any way for you to view your folio during the stay, the only way to know how much credit is left is to wait in line and ask at the front desk, or keep careful track of your spending. Also, the resort credit needs to be manually credited to your folio, and that didn't happen until I went to the front desk to enquire, I think maybe the concierge is supposed to do it when you tell them about the resort credit at the beginning of your stay, but mine didn't.
While we were there, I heard rumors that all of the restaurants were soon going to reopen, and so maybe that has happened. If so, that will dramatically increase the ways you can use the credit. We had expected to be able to use quite a bit of it by having dinner at one of the restaurants one night, but none of what was open was really a viable dinner option, and they closed really early, like 7 pm as I recall.
So long as you have a plan for how you're going to use them, the resort credit is a decent way to use options that you'd otherwise not be able to use. Have a great time at Nanea!
