I think the answer will be "yes, that's fine" but could I ask the clever folk on here a question? I'm travelling tomorrow from Herne Bay to West Malling and I have two options - either via Ramsgate or via Bromley South. Are both genuinely allowed? I don't want to be going almost all the way to London to then be challenged about going back to West Malling. Or the same for going away from the general direction of West Malling to get to Ramsgate. Thanks!
