Very good resort opposite Karon Beach
I spent 2 nights at the Moevenpick Resort. My room was clean and comfy with a balcony overlooking the garden, but there was nothing special to make it feel 5-star.
The pool area is really great though with separate pools and a waterslide. I also enjoyed the Sand Bar where you can eat some of the best pizzas in Phuket with your toes in the sand. Prices are reasonable too.
The Movenpick is across the street from Karon Beach. It's a lot cleaner and quieter than Patong, but doesn't have the same party feel to it.
