As we continue to plan our trip to Vieques, I have another question for you experts: We have a 6:40pm flight from SJU, to home. I am thinking about taking a 4:30 p.m. flight from VQS to SIG, which the website says arrives at 5pm. I would then taxi to SJU. This is on a Saturday afternoon. Does this sound safe to you, in terms of timing? We are 2 people, no kids, and probably only carry on bags (though maybe one checked bag).
There are some earlier options, but they would kill more of our last day in Vieques.
