We leave in 9 days for a three week trip that includes a 7 night cruise to Norway out of Southampton, England. We travel to London the night before (the Eurostar from Paris, tickets that have already been booked) and are staying near the St. Pancras station. The next morning we have to get ourselves down to Southampton, which I'm under the assumption is about a 1.5 hour train ride away (with one stop between). I'd like to go ahead and book the train tickets now, but H thinks it will be better to wait until the day of. For those of you who've visited the UK, what would you do? Thanks in advance!!
