Flying into London pre-cruise and only spending one day in London before heading to Paris mid-day the following day. Flying in from Memphis I have the option of two flights within my budget. One leaves 0600 and arrives 2245 and the second leaves around 1400 and arrives 0745 the next day. Which flight would you select and why? My concerns with the first flight is the late arrival time but would allow for us to sleep before touring all day the following day. My concerns with the second is not being able to check into hotel room and freshen up prior to touring. I'm sure we could drop off out luggage and perhaps sleep on the plane to overcome jet lag but with the first flight I don't know if we will be able to sleep when we arrive and will be too tired to tour. Please share your thoughts with me.
