Days out/theme parks

Isn't 3 a bit young to be worrying about visits to theme park. i doubt your DGS will really appreciate them.

At his age just visiting the local park, riding on the swings etc there and playing on the climbing frame will be much more fun, or take him for country walks, looking at leaves and insects in detail.

My memories of my DGS at that age is country walks and visiting the gardens of the local stately home, we collected leaves and talked about them. We also visited the local farm shop where they had chickens, sheep and lambs, goats and pigs

I just googled childrens attractions near Stokeon Tren and so many things cme up that were much mor appropiate for children under 7 or 8 - and a lot cheaper than theme parks.

Another nice day out would be to take the train from Stoke on Trent to Stafford.
When you come out of Stafford station, cross the road and you are at the entrance to Victoria Park.
This has all the traditional park features eg aviary, glasshouse with tropical plants and goldfish, a bowling green, a river with swans and ducks, plus a good children's play area, a big sandpit and a splash park during the summer.
There's also a café and toilets.
My minded children love going there!

Drayton Manor do an annual pass that also includes West Midlands Safari Park.

Twycross Zoo do an annual pass.

Tesco Clubcard vouchers can be used for half-price day tickets to Drayton Manor amongst many other attractions.

I booked half-price Sea Life tickets for my daughter and her family using Tesco Clubcard vouchers.

You'll need to read the terms and conditions on the individual websites, but hopefully that's given you a few ideas to start with!
