Exclusive hire venue ~110 people

Hi!

I’m interested in exclusive hire venues with accommodation (doesn’t need to be for all attendees).

Total attendees 100-120 people, budget can be >£100k

The venues I’ve found with a vibe I love so far are

Syon Park

Ashridge house

Kew gardens (no accommodation but lovely!)

Hedsor house

Also seen Euridge but seems to be full weekend hire only rather than 1 day?

Is there anywhere else I should be looking that will be a similar vibe or better?! Opinions on the venues above would also be great.

Ideally nearish to London

Thanks so much in advance
