If you like a hotel where it's very remote, peaceful with lots of privacy and beautiful settings, I would recommend the hotels up North.
I know that you have to go by boat back and forward, but then you are away from all the hustle and bustle... And whenever you want to go out and party in town, it only takes about 20 minutes to get there.
My recommendations would be Mata Chica, Portofino Resort, White Sands, Capricorn, etc. These are different resorts with different rates.
