Unfortunately the fact that you can't afford the holiday doesn't entitle you to cancel it. When you sign up for a holiday you agree the terms and conditions including the cancellation charges.
If the lockdown restrictions are still in place in July such that the Government advises against foreign travel then the company will be obliged to refund you any money you have paid.
If they don't cancel it and you are able legally to travel abroad then you'd have to either take the holiday or lose the money you have paid so far.
Here are some things you could try:
- Check the terms of your travel insurance if you have it
- See if the travel company would be willing to allow you to transfer the name on the booking if a friend or family wanted to buy the holiday from you
- See if they will re-arrange the holiday for later in the year/ next year
The last two would be at the holiday company's discretion. They are entitled to charge transfer fees/ admin fees etc but it might be better than losing the whole lot.
