So sorry to hear this happened to you. We returned from SXM to find our car seriously vandalized (almost $13,000 in repairs) in the parking lot at the Hilton Newark Airport. Travelers Insurance pursued it with the Hilton to no avail. To add insult to injury although Travelers did pay to fix the car, they raised our rate! We too had a “park, sleep, fly” package. It just seemed unfair that we parked in a secured lot attached to the hotel and the vandalism occurred through no fault of ours and our insurance went up. We did have a lovely time in SXM though.
