We had a really great time at Worldmark Kihei, and I would recommend it for anyone going to Maui who doesn't need the typical hotel experience. Worldmark is centrally located in Kihei and there is plenty of restaurants, stores, beaches, etc. that are within walking distance. Check-in was easy, there was plenty of parking, Tim's pre-reservation communication was comprehensive (we didn't need to reach out to him during our stay), and the whole stay was stress-free. I was particularly impressed by how well-appointed the kitchen was and the many gas grills on the property seemed to be well-maintained.
A couple of minor things: We noticed a musty smell in the room when we checked in (it seemed to fade, or we got used to it) and we called housekeeping two days in a row toward the end of our stay to have dirty towels collected and no one came to get them (we had no problem getting clean ones dropped off).
A few recommendations for anyone staying in Kihei:
Autie Snorkels for rentals (beach chairs, snorkel gear, etc.). We reserved online and got a great deal! Really terrific service.
Beach Street Cafe for coffee, acai bowls, and breakfast sandwiches.
Redline Rafting for whale watching. So much better than being on one of those bigger boats.
We had a rental car and found it very easy to get around the island and were able to find parking rather easily (even at popular beaches).
