Your child's inset days are secretly cheap holidays.
Real prices, checked October 2026
Up to66% less
at UK holiday parks, arriving the evening before your inset days rather than once the holiday starts (29–66% across the holiday parks we checked)
Inset Offset turns your school's term dates, inset days, half-terms and bank holidays into the longest authorised breaks you can take — and shows what the same booking cost on those dates when we checked.
Green means authorised — no fines, no permission letters.

How it works
1
Enter your term dates
Add your school's term dates and inset days. Takes about a minute.
2
We find the windows
We stitch insets, weekends, half-terms and bank holidays into the longest authorised runs.
3
See what you could save
For each window we show the options we priced for those dates, with the saving we found and where an inset day doesn’t help.
Savings are from prices we checked in October 2026 for 2 adults and 2 children, comparing the same booking on both dates. Prices change — always compare your own dates, and confirm term-time absence rules with your school before booking.
