My husband and I are planning a London-Paris trip in the fall. We'll be in each city 3 days and looking at the London and Paris museum passes to save money on the attractions. Trying to set a budget and not sure how much money we need, like per day. This wouldn't include airfare, hotel, transportation (between London-Paris) and attractions (if we get the passes). So guess it mostly means food and transportation around the cities. We're in our early 30s, so don't want to eat fast food, but don't need expensive restaurants either. Any advice or suggestions? I've read the travel forums on the London and Paris museum passes, looks like we would save money and time, but don't buy the extra travel passes and pay for metro as we go.
