I've recently left Thames Ditton.
Plus:
It's walking distance to Bushy Park and Hampton Court Palace/Home Park.
Can walk along the river to Kingston.
Kingston is close
Lots of pubs/restaurants.
Colets sports club.
Tiny Boots but handy as can collect online orders from there.
The infants and junior school are good but small intake.
A couple of playgrounds and greens to play.
Vera Fletcher Hall regularly holds concerts/plays.
Always felt very safe and it's very twee.
Negatives:
Trains only come twice and hour. Even though it's the second stop there's no guarantee you'd get a seat. It's a slow train into London, around 40 minutes I think but you could get off at Surbiton and catch the fast train.
I noticed the plane noise increase during the summer. I believe the Heathrow expansion will affect Thames Ditton but don't quote me on that(!)
Bus service is dire (I believe it may no longer be running or be even further reduced)
I found it a bit cliquey. I didn't do NCT when pregnant and it was hard to make friends.
High Street is pretty in sight but not the most useful of shops. There is now a Co op in Weston green which is basically Thames Ditton otherwise nearest decent shopTesco metro is in Molesey or Waitrose and Sainsburys in Surbiton.
Hinchley Wood is the most sought after senior school but there is no guarantee you'd get a place. If you wanted to send your dcs there you'd be better off moving to Hinchley Wood and sending dcs to HW primary.
In some respects I miss living there, it would be a nice place for my dc to grow up in however if I could afford to buy in Thames Ditton I would be able to afford Surbiton and I would choose the latter as it has more amenities Starbucks and train service into London (and south) is much better.
