Days out can be expensive, but there are plenty of ways to enjoy them without spending a fortune.
For the cinema, I use a 2-for-1 code, book the cheaper seats, and take a can of drink and some sweets from the shop. Total cost for the ticket and snacks? Around £5!
Last year, we went to Thorpe Park for free with four tickets we won through a Cadbury promotion. All you had to do was enter the code from a chocolate bar on their website. I ended up winning 4 tickets to Thorpe Park, 4 to Chessington, 2 to Legoland, 2 to Sea Life, and 2 to the London Eye! We used them all except the Sea Life tickets.
Both English Heritage and National Trust regularly offer free entry days through newspaper promotions. In fact, I have two English Heritage vouchers sitting in my kitchen right now! National Trust also runs online offers from time to time if you sign up. Take a picnic and a flask of tea or hot chocolate, and you've got a great day out for very little money.
The Sun newspaper also ran free ticket promotions for years. I used to collect the vouchers every year and took the kids to loads of theme parks without paying for entry.
We've also done plenty of low-cost days out, such as feeding the ducks, strawberry picking, having picnics, and visiting farms with free entry.
While things definitely cost more these days, there are still lots of ways to enjoy big days out for much less. It just takes a bit of planning and keeping an eye out for offers.
