We had pretty much written off the idea of taking a day-trip from London to Paris via the Eurostar because of time and expense (there are 4 of us), but I know my husband would really love to get on that high speed train. We will be trying to find a cheap flight from Scotland to London anyway (haven't decided whether from Glasgow, Inverness or Edinburgh yet) and I was wondering about flying to Paris instead, doing the Paris day-trip that Rick describes and then taking the Eurostar one-way to finish the day in London. We will be staying 3-4 days in London.
Is this worth looking into? Specifically, I wonder about getting from whatever airport we land at in Paris to the sights and then to the Eurostar. Would these connections be easy to do or would they eat too much into our Paris sightseeing time? Have any of you taken cheap flights into Paris and do you know anything about the connections?
Thanks for any advice.
