The Eurostar Train
We purchased round-trip airline tickets from the
USA to Heathrow in London because this was the cheapest deal
that we could find. After a week in London, we
train from downtown London to downtown Paris.
The trip took less than 3 hours. It cost us $300 total for 2 tickets to
Paris and 2 tickets back to London. The train is very nice and
comfortable unless you get backward facing seats, especially those that are not
next to a window. This is what we ended up with, but we switched to nice
forward facing seats next to a large window as soon as the train started moving
because the train was only half full.
A better option would be to fly from the
USA into London, then take the EuroStar to Paris, then fly from Paris
back home. This saves a valuable day of your European vacation from needing to
be spent traveling back to the Heathrow airport. We
could not do this with our frequent-flyer miles however.
