I personally prefer HHI I think, especially off season, it's still a bit warmer in Feb, but no major traffic or lines etc. Then again, I was in MB in April, so of course crowds would be different. But HHI seemed to have more stuff I like to do, easy drive up dining, easy parking at 2 nature preserves, an hour or so from Savanna. That said, MB was "fine" but I didn't love Ocean Enclave - I mean, sitting on the balcony looking at the ocean was nice, but getting in and out and the waits for valet and the waits for the elevators along with not much at the resort itself wasn't my speed. I think I actually enjoyed Surfside beach more at the Worldmark/Wyndham there. That ended up closer to better dining IMO, and I did find a neat museum and gardens about an hour away from there.
So - Ocean Enclave is nice in the units, and fine if you're going to just hang out on the balcony looking at the ocean IMO. Otherwise I'd try and get the more available and cheaper Surfside locations which is closer to Murrels Inlet. I do plan to go back because there are a lot of deals if I don't need to be ON THE BEACH, and to check out more of the nature parks this time. I might try for May though.
HHI is nice if the weather cooperates. That's a bit of a crapshoot off season, but I don't know how late into the year I want to try and book a deal, nor do I know how quickly the traffic gets real bad. I might try pushing into March some year, but right now that is probably 2028 based on my planned trips earlier in the year already set up in 2026 and planned for 2027. Though 2027 is kinda shooting for April in New Orleans so maybe I could try something like HHI end of march to Destin or something like that to New Orleans mid April. Or maybe I'll try and fit in the second half of 2026 in October or something.
Digression on trip musing over, I do also think HGVC doesn't really need another tower in MB - it's already eminently bookable - I guess "it's new" would be the pitch. But if the point costs are over Ocean Enclave I don't see it being that appealing to anyone paying attention.
