London - what should we see on our own?
My husband & I will be on the September 27, 2015 Cruising the Seine, Plus Versailles, Paris & London. We will arrive one day early to London & will do our own sightseeing. We have our final documents & for our 1st tour day it says; "guided sightseeing of the city's iconic landmarks". Can Tauck be more specific so we don't repeat something in the short time we have there? Is the Tauck guided tour mostly a drive by? If so....what would you recommend we explore further? Any suggestions will be greatly appreciated. Thanks!
