I like this trip as it covers almost all of the highlights in London and Paris. I only have 3 to 4 days in Europe. Do you think I can do most of the highlights in such a short time? If no..which one do you recommend to take out from the trip? How long does it take to visit Madame Tussaud's? How long does it take to travel from London to Paris? Which airline are you flying with? Please reply ... Thanks!
