Any good UK honeymoon suggestions?

[Littleblurry]

DP and I get married next year. We have small children so dont want to stray too far but we have 3 midweek nights after we get married that we can have as a mini honeymoon.

We would like a) somewhere we can chill out and relax and chat about our wedding and read our cards. b) be somewhere near a good day/night out without driving one of the days. (Could be London for a show and dinner, or a lovely country walk with a great local pub). Oh and we also like hot tubs!! The south of England would be best for us location wise. Open to the idea of a self contained Airbnb or a hotel.

Any suggestions very welcome! Budget around £200 per night but could go more for the right place.

Narrow boat from Tewksbury. We did this for our honeymoon. No one can get near you ! Bliss...

The sands Scarborough 5* luxury apartment right on beach
As you said you have 3 kids, ideal
They have 3 bed apartments with hot tub and they also gave play station if kids are old enough

There’s a bar underneath where you can eat
Also a cafe underneath
A pub down beach route 10 mins walk
Whitby not far, nice harbour

Thanks for the suggestions!! Sorry I wasn't clear in my OP- the kids wont be coming with us (hence why we dont want to be too far away)

Either Pipe & Glass at Beverley, or Gilpin Hotel in Crook. Both Michelin star restaurant hotels, and rooms are secluded with hot tubs.

Gilpin is next to a lovely old coaching house called The Wild Boar. Superb food here and a lovely woodland walk leading to a small tarn. Walk away from Gilpin in the other direction and you come to School Knott, where you have the most spectacular view of Windermere.

The Wild Boar also has room ls, one of them has a massive 5ft copper bath!

Jersey, Channel Islands. Great for our first and second honeymoon. Just pick a hotel that appeals to you.
