Just so I understand this fabbr1, you wanted Seaborne to inconvenience everyone on the STT - STX runs so you and your family wouldn't be inconvenienced,and you could "enjoy" (your words) a day in your hotel in San Juan? With zero regard for those passengers that travel back and forth, sometimes daily, between STT and STX. Maybe the mom trying to get home from work to get her kids from school, etc.
I empathize with you for the act of God (stuff breaks)that impacted your trip, but I think Seaborne made the correct business decision.
