I managed driving a stick shift on the wrong side well enough (in three countries, I think). What I found surprisingly important was that the shift and clutch are BOTH on the left over there; changing what had been a cross-body activity into something happening all on one side made a surprisingly big difference. (And then pushing the shift AWAY from me to get into first was kind of weird, too.)

I'm a big fan of Kew Gardens also. I also like Greenwich, and the maritime museum there.
