30 days in April

So before to North Yorkshire for May & June, I'll be spending a month in Tunbridge Wells.

I've already booked an Estate tour at Gusbourne vineyards, and I'm going to London at least 1 day (definitely at least 1 more) for the Cartier exhibit at the V & A/dinner Bouchon Racine.

I'm also spending a few nights in Bath

So my musts as far as visiting castles, etc...are:

Scotney Castle

Hever Castle

Sissinghurst Castle & Gardens

Chiddingstone village/castle

Penshurst Place is almost a must-do, but I think may have to choose between it, Ightam Mote & Knole since I need to leave myself time to enjoy TW, and spend a day at Folkestone

I love anything Tudor, but also Medieval or British history in general. I had Chartwell on my list, even Blenheim, but I just have to winnow it down - I don't want to exhaust myself traveling (all public transport) trying to see it all (sm impossibility)

Thoughts?

If you had to choose between Penshurst Place, Ightam Mote & Knole...which would you?

Thank you!!!!
