A prompt cashback payment
I'm always a bit hesitant booking a skiing holiday with Crystal after a nightmare trip some years ago. However, things have moved on since then and the latest holiday was very enjoyable (apart from the weather). Crystal managed the trip very smoothly. Unlike other potential operators, I was even able to find a departure that suited us from our local airport. To top it all, they were pretty prompt with their cashback payment. So, thank you Crystal.
