@ThisTealLeader , I really feel for you. Your situation reminds me of my DN, who at 17, did similar to your DD and told us last
min that she was off to Mykonos.
She had little spending money, she did have travel insurance.
It transpired that she spent the majority of her spending money at the airport on a pair of designer sunglasses. When she got to the hotel, she and friends then got on quad bikes, she lost control of hers, fractured her arm. Ended up in hospital. Insurance was void because she was underage, age limit was 18.
My sister and I (not her mum, my other sister), had to pay hospital costs and provide money for the rest of the holiday, half of which she spent in hospital.
She is an adult now, she has autism, she is high functioning, she has good jobs but is erratic, messy and still impulsive when it comes to travel. She’s off next week on another last minute holiday. There have been other incidents but none as bad as that.
Oh, once she was appealing eviction from her hotel room. She’s a nightmare.
Good luck, I say. But just keep extolling the importance of safety. Do her friends offer you some assurance. I did see that you posted her friends had some concerns also.
