I have a wedding on Saturday at 2.30pm in East Sussex close to either east grinstead, tunbridge wells or Cowden (trains from either London Bridge or london victoria then have to arrange a taxi I think).
I arrive in london in gatwick at 8.30am.
I have a place to crash / leave stuff at in Farringdon, London (EC1) but not sure if it’s worth going there in between? Am bringing very simple wedding guest dress with me (boho garden wedding with v relaxed but stylish and lovely bride) so can get ready and stick a bit of mascara on anywhere en route if you see what I mean.
