My friends are supposed to be going on a Siblu holiday to the south of France next week for 3 weeks. Siblu phoned them today and cancelled! They say the caravan they were booked in is no longer available so they can no longer accommodate them. They booked this holiday last November and are devastated. We have booked to go to the same site (for one week) and are meeting them there. They have flights booked separately. Siblu have offered them alternative accommodation on another site but it is too far away for us to meet them and is only 2 star (as opposed to 4 star).
Has anyone any suggestions? We have checked the terms and conditions but it looks as though legally they can do this.
