We had an ocean view room and it was quiet enough. Other than the waves crashig which was great, you mostly hear luggage rolling with guests checking in and out. Walking around at night seemed safe. Of course, caution is always good wherever you vacation.
We were there for a week, and quite a few guys approached us on the beach selling crafts and excursions. But, I was only offered weed one time. I said no. All the sellers were respectful and usually accepted a "no thank you". The weed thing might have something to do with age. A younger person may get more offers.
I have no issue with the rating, either. You are in the Caribbean! Hotel is comfortable clean, good food , well situated with wonderfully friendly staff and you will want for nothing, so what is the problem?
