Bummer about that return trip but glad you had a great time nonetheless. We’re heading to BVI on Wednesday for a 10 day trip and have similar concerns about transiting San Juan airport. The TravelSafe app won’t let you choose a duration of less than one day and requires an entry for lodging, but we’re just switching planes! I emailed the contact they show on the site, but haven’t heard back. Any insight from this esteemed group would be greatly appreciated!
