We will be traveling from London to Chipping Campden in the Cotswolds this spring. On the way we would like to make a side trip to Blenheim Palace. It’s doable using public transportation but we will have our luggage with us. Is there a place perhaps in Moreton in Marsh where we can check our bags?
Your train from London will stop in Oxford, which is where Blenheim is located; just a short distance north of the city.
If at all possible, plan to spend two nights in Oxford, and take the bus north on the full day you will have. Oxford is a great place to walk around during the time you are not at Blenheim.
If you don't have time for an overnight in Oxford, there will be luggage storage places in Oxford (Google "stasher" for Oxford) and storage available at Blenheim.
Travel onward a short distance to Moreton-In-Marsh from Oxford by train.
Bus or taxi from Moreton on to Chipping Campden.

And this was my previous response- They have lockers at Blenheim Palace-
You are permitted to take a small bag only into the Palace. For larger bags, we ask that you use our locker service. Lockers of different sizes are situated outside the Blenheim Palace shop. We charge depending on size. Pricing is £4.00 for a small locker, £6.00 for a medium, and £8.00 for a large locker for 4 hours of storage time. We charge an extra £2.00 per hour over the 4-hour period.
That way you can take the train to Oxford, bus S3 from the Station to Blenheim and then the S3 back to Oxford Station for your forward train to Moreton, without having to go into the city to find a luggage drop point.
How are you managing your bags on your walk- carrying them (backpacks) or using a Sherpa service?
Maybe e-mail Blenheim to check that their large lockers fit your backpack dimensions?
Are you staying in Chipping Campden (per your original post) or Moreton. If in CC there are buses from Moreton Station at 1725 and 1845.
This is your original question about your walking holiday-
