We are signed up for a 'Best of London' tour in October. Our son was in London last year and relates that the guard changing ceremony at the Tower involves standing over two hours ( I have ankle issues from an injury last year) and there are no restroom facilities nearby. Is it possible to simply skip this activity and rejoin the group later in that day?
Also do your buses for the tour have restrooms? Hate to ask but when you're older, it's nice to know.
