Mentioned in another holiday thread but a word of advice for people who have something package related booked for this year, you've only paid a deposit but have no intention of going.
Don't cancel it before you absolutely have to. There's gonna be so much disruption and schedule changes etc which means the tour operator might cancel you before the balance is due, which means you'd get your deposit back in that instance.
There is absolutely no point cancelling early as 99% of the time your liability is the deposit, and that remains the case regardless of if you cancel 3 months before the balance is due or 3 days before the balance is due.
