Maps: from Winter Wonderland in Hyde Park to Charing Cross Theatre.

I expect we'll spend all day at Winter Wonderland in Hyde Park, eat and shop, and not leave until we rally have to, which will be about 6.30, an hour before The Woman in White starts at  Charing Cross Theatre.

Maps: from St. Giles to Winter Wonderland and Cinderella on ice

So until a couple of weeks ago, I'd never heard of Winter Wonderland in Hyde Park, but my friend Magnus was looking for a monday matiné, and Cinderella on Ice came up!
It looks great, and we are planning to leave our hotel, the St. Giles, early in the morning, stay all day - of course see Cinderella on Ice, at 2 o'clock -  and then leave about an hour before Woman in White at Charing Cross Theatre starts.
