I stayed here last November, so fairly recently, but not much different than the last one in Oct 2017. I won't go back through all the prior posts, but here's my quick review:

- 10 minute taxi ride from the airport
- On sort of an odd bay that has dramatic tides. You can walk out at least a hundred yards during low tide. So not really a beach where you can swim or get any size waves.
- Very nice resort overall, but very isolated. Long walk or short taxi ride into town, you won't really see anyone on the beach that isn't staying at the hotel.
- Rooms seemed very modern. As a Gold (at the time) I booked a garden view room, and was upgraded to a very nice pool side room, which had a private patio. The patio had a table and chairs as well as a 2-person chaise lounge/bed, with canopy. Large hedges on both sides, so it was private except for the view and walkway to the pool which was about 25 feet away. Great room if you don't feel like splurging on a villa.
- Family friendly, but not overrun with kids.
- Restaurants were all very good, although I think the upscale place (forget the name) was overpriced compared to the others. There was a fantastic Thai buffet one night. Definitely take advantage of that if you stay here. The breakfast buffet was also very good, but expensive, even with the elite discount (compared to the Marriott's in Bangkok where I got almost similar quality buffets for free). A pad Thai station was set up by the pool one day at lunch, which was kind of fun.
- Very friendly, good service, what you'd expect in Thailand.

Haven't stayed at the Ren. From what I can tell though, neither has a lot to do in the surrounding areas. If you're looking for nightlife of any kind, I probably wouldn't choose either of these hotels. If you want to relax, mainly stay at the resort, and forget the rest of the world for a few days, the Nai Yang fits the bill.
