Head out to the Cotswolds/Oxfordshire - it's beautiful this time of year.
Burton on the Water has a bird zoo that's fun and one of the oldest tea rooms in England. Cream tea is not to be missed. Awesome little shops. There's also a little cemetery with a memorial to the US pilots who trained at RAF Little Risington.
Warwick Castle is a great excursion in the same direction. Beautiful displays, and the Earls of Warwick were kingmakers.
You can also hit Stratford upon Avon in the same trip.
Blenheim Palace is a great experience. Winston Churchill grew up there. The house is magnificent and the grounds are amazing. It's built on the former royal "lodge" of Woodstock, and the history there is fabulous.
If you're a Harry Potter fan, you can hit Warner Bros. Harry Potter studio tour in Oxford as well.
There's a ton of things to do in the area and it is just as picturesque as you can imagine. Green pastures dotted with sheep, adorable little villages and a ton of history from early Britain through WWII. It's been the playground of royalty too.
One of my favorite places on earth. I was born in London, but I love Oxfordshire.
