Have to agree with windguy on this one - Just bought a ticket to Toronto for $250, so not sure how much lower that can do.
Also agree with windguy that Cabarete is down, and can't help but feel that it's a big part due to Airbnb. As all the hotels have either closed (because they can't compete with airbnb) or turned into condos (adding yet more to Airbnb) the end result is no one advertising Cabarete. Without that, numbers will continue to stay down.
The way I watched it happen was the business was spiraling down and nobody was refurbishing the hotels. As the occupancy rates dropped, the owners of hotels converted them to condos and sold them. Then Airbnb came along and people rapidly started to use them, which is good for the consumer that does use Airbnb because the prices got driven downward over time.
