Hi everyone. We're planning to go for a day trip to Dover while we're staying in London. We'd ideally like to go to Canterbury, then go on to Dover. While in Dover, we'd like to go to the castle and also see the white cliffs. Is this too much for one long day for a group of three adults? Would it be better to eliminate the stop at Canterbury? We've never been to England and there's SO MUCH we want to see, but we also don't want to pack so much in that we're exhausted and can't appreciate things.
Also, I've read many comments that say that Dover itself is not really worth visiting, so is it possible to see the cliffs from Dover Castle, thus avoiding the town altogether, to save time?
Any advice on the best mode of transportation for the day? We could rent a car if that's best, but we're certainly open to trains and such as well.
