You can try to propose an amount and ask to raise up to Management Level. I had a colleague who got some sort of 3+1 deal like pay 3 nights Club surcharge and get it free for one day, but he was quite persistent and a bit of a PITA. Too much time and effort in my book.

Overall, some folks find it worth the money, but you got to really go for every meal and clean up the place to get your money's worth it in my book. But hey I have seen some people finish 8-10 drinks each during the cocktail hours and that can add up quickly if bought at regular prices at the hotel bar.

Total comes to around 160 USD all in per room per night for a "better" room (more like a bit different furnishings and maybe better toiletries in some folks eyes) plus Club pool access, transfer (now also offered for certain pre-paid rates of 3 nights or more) and of course Club lounge (breakfast in lounge, restaurant or room; afternoon tea, cocktails and snacks in evening and tea / coffee / non-alcoholic stuff during the day).

Of course, if you plan to be outside the hotel a fair bit and won't be around for all the meal / drink offerings apart from breakfast then it is not worth it in my book. If someone just lounges and relaxes all day at the resort without venturing much outside then it can be a decent value though nothing awesome.

Overall, I'm more on the "a bit too steep side", but YMMV. I would consider it maybe if it helps avoid switching rooms between points nights and paid / BOGO nights, but depending on how many nights one is talking about you could always try to negotiate it for free first
