From Germany we drove to Calais, France to catch the ferry across the channel to Dover, England. We used P&O Ferries (found
HERE) to book our tickets ahead of time. I highly recommend doing it before you go, I hear they are double the price if you buy your tickets on site. You don't have to be there on time either like the Chunnel (found
HERE), which is why we didn't use it. We booked a time for 13:50 and we could show up 4 hours before OR after our scheduled time. It worked out quite nicely, especially since we missed our appointed time.
Don't forget your passports either - Very Important!
Our first day we visited the Natural History Museum (FREE)
It is absolutely perfect if you have children - our kids LOVED it!
