The best entries from this week's readers' travel tips competition (there's a two-person Jack Wolfskin tent for the best one) will help make up next Saturday's special issue on 100 great things to do with the kids in the school holidays.

We are looking for UK stop-offs that will make the journey not just bearable, but enjoyable for families. Think green spaces, child-friendly attractions, lovely cafes and picnic spots to take a breather from the holiday traffic.

As you've noticed, we're changing things a little while the Been there website has a bit of a revamp and we'd like you to share your tips via GuardianWitness. All you have to do is click on the blue 'contribute' button. If you're sending text only, make sure you choose the text tab. (It's fine to send a photo with your tip if you'd prefer – but it's the tips we'll be judging!)
