V&A is definitely on our list. I've had many recommendations for it. Both museums are covered by our London Pass, but V&A is first on our list as far as finding time goes
I hear it's snowing in England and Scotland, and, alas, my snow boots are packed in my storage unit, not anywhere near my luggage (also not the most comfortable for sightseeing, I would imagine). Since I got these nice breathable sneakers recently, I'm going to have to buy some boots in London. Today I'm really missing my old Sketchers, which were perfect for slipping on and off at airports and solid enough that my feet only got wet if the snow was higher than the top of the shoe. But they stopped carrying those.
ETA: I am discovering that these phone cords Santa slipped into my stocking (to replace the broken & lost ones that came with my phone) are not very efficient for charging my phone. I didn't entirely register that the speed was lower when charging them in my car (though I've been surprised at charge level being not as high as expected after driving a bit), but sitting in this airport for forty minutes with my comp plugged into the wall and my phone plugged into my comp (while my phone gives me an internet hotspot --it's very synergistic), my phone was only down like 6% power and still is only at 99%.
Oh, well, after the trip, I'll have my charging dock at the AirBnB, so it's only the 13 hours of flying where I'm worried about the charge for both devices. My watch should be okay, since it'll be on airplane mode and not doing anything but telling (Pacific) time.
