There are more than enough reasons to justify a grand splurge on a trip to London. One of the most dynamic and diverting (and most expensive) cities in Europe, it boasts much-lauded restaurants, fantastic hotels, great weekend markets to stroll through, and buzzed-about shopping. And even though travelers can enter museums and gorgeous parks for free, most of these activities come at a premium. It doesn't help that the British pound is no friend of the American dollar.
