A Leicester family who have spent more than £12,000 on a holiday of a lifetime with collapsed firm Sun4U say they are worried it will not go ahead.
Kellie Bugby was due to travel to Alcudia in Majorca with 35 other members of her family on 31 August.
She said the family are frustrated as they do not yet know what will happen to their booking.
Sun4U has apologised to its customers and told them to contact claim handlers for the travel association Abta.
Ms Bugby said there was no special reason for the holiday but she had wanted to bring the five generations of her family together for years.
"We have never been away in a big group like this before.
"We all live locally but it is still hard to find the time to get together with work and children."
She said the family were hoping the holiday will go ahead or that they will be able to re-book the same dates.
The youngest members of the party are Ms Bugby's five-month-old twin nephews and the oldest is great-great grandmother Lola Kemp, who is in her 80s.
Ms Bugby said: "We can't get hold of any organisations to find out what's going on, so we're a bit worried."
Sun4U said it had suffered significant losses as a result of the volcanic ash cloud and the failure of Goldtrail, which was one of its major tour operators.
Approximately 1,200 customers are stuck abroad, most of them in Spain.
