This video is so informative! I'm planning my clients travel to the island for July. This will help them make up their minds because you give the average price per night.
Depends on the time of year of your stay, discounts that may be applicable, and which site you choose to book your stay. Could be between the range of 950 to 1300 dollars but you should check as many sites as possible when searching as not to miss out on any discounts. Hope this gives you a barometer.
