Has anyone done the Free Tours by Foot Tour, specifically the London-all-one Tour? My parents, bf, & I are going to London for the 1st time & we want to take advantage of this. It's free, you tip the tour guides based on the service they give you. I've read the reviews in TA, but i don't see reviews about the London-all-in-1-tour.
Thanks! Any tips and suggestions will be greatly appreciated! :)
