We're going to London for the last week of July and first few days of August. We wanted to go and check out Paris as well and I am trying to find Eurostar tickets for the Wed-Sat July 28 - 31. It's coming to $508 US when I check the Eurostar site. Anybody know of any way to get much, much cheaper than this on Eurostar?We're not so interested in doing a flight because of the amount of time we would waste at airports. Rail seems to be a much quicker way to go.thanks in advance for any help.
