I didn't reply before because I expected others with more experience would have responded.
FWIW: I have only stayed at the Las Vegas Blvd location. It's a long ways south of the "action," but with Covid going on, I'm not sure how much "action" there is right now anyway. The room was nice, if underwhelming, in an "average" WorldMark sort of way. No surprises there. It was a long hike from the parking area to the room - it's a big resort. You'd want to plan your parking better than we did. We didn't use any resort amenities, so I can't speak to that. Based on the screaming kids in the pool, my guess is that they were having a good time. I'd stay there again, probably over the other WM Las Vegas resorts, just based on the location. I'd rather travel to the insanity of The Strip on my terms, than being near the heart of it.
(Not much help, I know. But there weren't really any complaints about the place, but also nothing that made it exceptional for us.)
