We have one day in London - we arrive on Friday morning at 8:30 and must leave early Sat. morning for Paris. (Yes we know one days I not enough time, but it's what we have to work with.) Any suggestions on where to stay, and what to do that we can cram in to one day. Not really interested in museums as they would take too long. Would one of those hop on hop off bus tours be best? Would probably like to see Buckingham Palace/Kensington, and anything else you might suggest. We haven't decided whether to take the train from London to Paris or fly the following morning. Thank you!
