Overall, my group of six 30+ adults was very happy with GC #170 and would stay again!
The location was *perfect*; the beaches close to us (Wailea Beach in particular) had that perfect soft sand, clear water, gentle tides, etc. that you want in a beach. We also saw sea turtles every time we went down there! The provided beach chairs from GC #170 were in good condition and comfortable.
There are also a couple of shopping centers close by, which had coffee shops, restaurants, grocery stores, etc. It felt very safe to walk to any of these places, including in the early morning and evening.
In relation to the rest of the island - it took about 10 minutes to get to Kihei, 30 to Kahului, and 45 minutes to Lahaina, and 25 minutes to the Ma'alaea harbor.
For the actual condo, it is a bit tired and could use a few more updates, but as a place to sleep, play games, and occasionally eat, it was perfect. Plenty of seats for everyone to comfortably sit. Window AC units were in every room except the twin room, which was my friend's only complaint. A provided plug-in AC unit (like a Dyson) would be an easy fix to that issue. All six of us thought the beds were comfy, and there is a new kitchen counter (granite) as well which was nice for cooking. I really enjoyed eating breakfast out on the lanai every morning.
The pools in the complex were on the small side, but never crowded or hard to find a chair. Overall the complex was very quiet, had relaxing energy, and was beautifully landscaped.
