First let me start by saying I'm new here so there are many things I don't know. So please excuse me for any mistake/rudeness etc.
Airfare = $958.20
Eurostar = $65 (Feb 20th)
Paris 2 day Museum pass + 3 days Metro = $104.65
London metro / museum pass = Open
Lodging/food in Paris = open (Check in Feb 16th to Checkout Feb 20th)
Lodging/food in London = open (Check in Feb 20th to Check out Feb 24th)
Walking tours in Paris = open
Walking tours in London = open
Can someone give me ideas on where to stay and which tours to take? I'm thinking of taking walking tours the first day to get myself familiarized with the areas. So I can pick and choose where to visit later. Please help me with your helpful suggestions and safety tips. This is the first time I am traveling alone in Europe so naturally I am a little nervous.
