If you know when you'd like to travel, tickets can be booked online via the Eurostar website. The tickets are printed and collected from kiosks at the St. Pancras terminal in London on the day of departure.
If you have flexible travel plans, you can purchase your ticket at the station, receiving a "last-minute fare" discount, though this is subject to availability and is not practical for travel over holidays and most weekends.
Eurostar has up to 20 trains per day traveling to Paris, so you should have no difficulty making arrangements for any given date. Early and late trains tend to cost less than those departing between 9 a.m. and 5 p.m.
Once tickets have been booked, plan on arriving at the station 30 to 45 minutes prior to departure. You will be responsible for your own luggage for the duration of the trip.
The high-speed train makes reaches its destination in just over two hours. The train has several snack bars serving a limited, but decent, selection of refreshments and offers multiple restrooms in each car.
