I will have one extra day in London in June and I'm anxious to see Kew Gardens and Hampton Court Palace. I understand there is a train that goes between the two and takes about an hour of travel time.
Is it reasonable to try and see both? Not all of them, of course, as I believe they are very large. But could one at least get a reasonable overview? Is there a tram tour, etc. at either one or is it all on foot? What is the least amount of time that should be allowed at each one?
