January Honeymoon, best bang for our buck hotel?

Looking for a warm and romantic honeymoon hotel, bonus points for turquoise water! We are travelling from Toronto and just going for a week. I have luxury taste but trying to find something under $800 USD a night (could increase for all inclusive). The actual hotel is the priority, looking for a place that is modern and very aesthetic. We are more pool people as opposed to beach and we love spas. Trying to get a honeymoon suite without breaking our budget!
