Barbados is quite strict on when they will start letting US tourists back on the island. Covid-19 is still rampant. So, we just rebooked for April 2021.
Do you really believe that in April 2021 the Pandemic will be over? We don't know yet how effective any vaccine will be and how fast it can be rolled out.
Again, I still would be hesitant to book anything in 2021.
