Short honeymoon in the south west

[Seriously79]

Getting married next April (hopefully this craziness will be over by then) and have arranged for the kids to be taken care of for 2 nights. Would love to stay somewhere 'different' a treehouse, boat, castle just something a bit unusual.

We are in Bristol and happy to travel for a few hours.

Any recommendations please?

There’s some lovely old train carriages you can stay in in Petworth. It’s a hotel and breakfast is served in the old station. my husband and I enjoyed staying there a number of years ago.
