What happened to alyt?

For our original poster, I'd offer this itinerary - London, Amsterdam, Paris, Venice. My reasoning, they are amazing classic cities in Europe, but secondly they are places I have done successfully solo female and had a blast. Challenging but do-able. And with the luxury of 25 days would not be too rushed. Talk about architecture, museums, and food!
