Can't give particular advice from the industry but as a tourist who lives here now and speaks with family who comes to visit, I can say the Dominican Republic plain and simple is not as cheap as it used to be, and that's the reason many of my friends and family are going to other places that cost about the same and they feel offer more. I stay in PC, and I can say prices for everything here are waaaay higher than 6 years ago when I visited. Inflation is universal, but when many people were visiting due to expected low prices and then they find things more expensive than in the US and in some European countries and other Caribbean islands and Latin Am countries it makes the DR enter a different tourist bracket. Could be wrong.
