Family events/good things to do for a toddler in Oxford/Stratford Upon Evon/Warwick

[user586837]

Travelling back from Windsor to Manchester tomorrow. Thought we would break the journey up for our toddler by going somewhere nice. We originally thought of The Children's Play village in Warwick but it's full.
Wondered if anyone knows of any similar places or outdoor places/events in surrounding areas I mentioned. Or basically anywhere between Windsor to Manchester?
TIA

Stratford park is nice. You can walk/play by the river. Hire a boat.
There is a play park which used to have a paddling pool (I'm a bit out of date).
The butterfly farm is on the same site and last summer there was a big sight seeing wheel in place.
Lots of cafes etc for ice creams.

Lots of things. Warwick has the Castle of course and St Nick's Park is brilliant with play area, rides, boating and a splash pool. Lovely little museum in the market square although I don't know if it's open on Sundays.
In Stratford the park, river and butterfly farm are all close together. The butterfly farm can feel oppressive on hot days but last time I looked we were set for rain tomorrow. The Shakespeare properties are good, Mary Arden's house probably best for younger children. MAD museum is excellent.
Oxford the Pitt Rivers museum and Natural History museum are in one building, great for kids. Again there is boating and there's the Ashmolean which I have never visited. Don't know about parks. Blenheim Palace near Oxford is utterly amazing.
Leamington has Jephson Gardens, Kenilworth Castle is great.
Hatton Adventure World is good though pricey.

Hatton Adventure World. The programme of events changes with the seasons but includes petting and feeding farm animals, inflatables, a tractor safari, indoor soft-play, pony rides, guinea pig village and a puppet theatre. There are too many different activities for me to mention them all so check out their website.
Umberslade Farm Park is very similar to Hatton. It has just got a new indoor play barn with a sand pit.
West Midlands Safari Park is excellent for young children. Apart from the drive-through safari, there's a really great feature especially for younger children called Boj's Giggly Park www.wmsp.co.uk/boj-gigglypark/ The discovery trail is also good for small children www.wmsp.co.uk/discovery-trail/

Have just checked and actually it's supposed to be dry until tomorrow evening. Of course it says it's dry now and I've just run into the house squealing from the heaviest rain I've seen in this country in a long time!
