We are still planning on going.
We are a fully vaccinated family of 5 leaving from three different cities in the U.S. on three different airlines for SXM and then SBH on Friday, August 13. And, while there are many tests to pass, forms to fill out, lines to wait in, planes to catch, and restrictions to deal with, the thought of relaxing by the pool at our villa after completing all of these necessary obstacles seems to make it all worthwhile.
Will there be some anxious moments as we await the test results on the back-end of the trip? Absolutely. We are not concerned about our health but the inconvenience and impact a delayed return (due to a positive test result) would cause to our daily lives. Many work and work-related commitments await. Kids need to attend college. Dog sitter has other plans, etc. But, that will not stop us from going and enjoying this island paradise.
Just my $.02, your mileage may vary.
