I see the Thames Barrier has several closures scheduled throughout this
year, but only one of them is a "full tidal closure." Is it worth trying
to go during the full tidal closure, or will I not notice the difference
going some other time?

Since the Thames Barrier is important to navigation I think it falls
under "transport."
