The most convenient ways to travel to Paris from London is either via plane or train. If you’re not a fan of flying then you have the option of taking the Eurostar which takes just under 2hours 30mins (http://www.eurostar.com/us-en), not too far off the time of taking a flight. Paris is a wonderful city and often described as magical. The city is especially pretty in the evening when the sun goes down and the lights come on. It’s holds an air of mystery which is inviting and encourages you to explore in all the best ways!
