I am arriving at LGW on 12/16 (Boxing Day) at 8:30 AM and am interested in going to France to spend two and a half days in Paris before returning to London for another four. How long should I allow for customs and travel to the St. Pancras station to catch the Eurostar? What are my options to get from the airport to the train station? Are there other options I haven't mentioned?
BTW--I looked at flying open-jaw, but the total extra cost with airfare + one-way Eurostar was about $1,200 pp. I'm a teacher, so I have more time off than $$$ to spend. :-)
