Platinum Elite here looking to stay at either W or St Regis this coming September for an anniversary but struggling on which to choose and looking for advice. Wife and I are looking to scuba dive but otherwise low standards and looking for that once in a lifetime experience. I currently have about 200k points but have plenty of Amex/Chase points to transfer to Marriott for the rest.

I have one points advance booking at each hotel: 5 nights beach villa at the W for 240k and 5 night OVW bungalow at St Regis for 440k (would prefer GV prob but no availability). Opportunity cost of the extra 200k pts I put at about $3,000 I could’ve used for other travel, but I don’t want to miss out on St Regis OVW. W seems good enough to me, but anyone have any advice?
