My husband and I were in your resort and had a good time because we are not picky!!!
Let me start with the good:
Front desk 120% FANTASTIC
Food very tasty and lots of variety
Very clean, rooms done on time and properly
Beautiful beach and pool
Fantastic grounds, amazing sitting area specially around the lobby bar.
Now in my opinion things you need to improve or change:
Your staff does not ever say Good morning, How are you, Thank you or even a smile especially at the buffet and the lobby bar.I should not have to wait 30 minutes for a drink or have to get up to get my own.
Another negative is the weekend guests!!!
They have no manners, when in the restaurants they use the serving spoons to taste the food. In the pool you have posted signs asking guests to shower before going in, and they go in with Tshirts or like I saw myself in there underwear, if you want those guests they should book a vacation like we do.
I have been in Dominican many times ( Punta Cana, Samana and La Romana) and so far your resort was the worst, in my opinion you don't deserve 5 stars.
