I guess DR govt is hungry for money, that's why the overstay fee went up so much. I think the overstay thing needs to be abolished.
Create a new tourist stay program, more effective and affordable. The first 90 days, it's free no fee. then if you want stay 3 more months, add $100. If you want stay year or more, that's $250 per year up to 5 years. Now, that's affordable and less BS. More transparent and simple for all tourists.
I would also drop the $10 Tourist tax and also I would cut the Airfare DR taxes in half. Then you will see tourist will start flocking here more than ever.
