I really have a hard time understanding DR stance.
Ok, we get that the country rely on tourism, so as other countries, yet they have been more vigilent of whom they let in (come on now, at least ask for a test !).
Other places, have been totally shut down to tourism such as Thailand and Bali. No doubt that it has been devastating, but I have the feeling that when these country re-open this summer and have a better handle of the pandemic and higher vaccination rate of their population, tourists will pick these countries over DR (for the North American market, other islands over DR)
Also, it's been a year and studies have shown that curfews in developing countries are not as effective as previously thought.
I hope I am wrong and I don't have the answer, but it looks to me that DR open-arms policy may backfire on the long run.
