I have to travel to Croydon next week. tfl's Journey Planner's
best suggestion has me bussing to Uxbridge, Tube to Hillingdon, then
some mysterious express bus to Victoria, thence rail to East Croydon.
A bit over two hours.

Poking around various maps I wondered about Piccadilly from Ux to
Earl's Court, District to Wimbledon, and Tram to Croydon. No idea yet how
long that would take.

Anyone (Paul?) have a better idea?

"CR9" isn't a physical location - it's the postcode for businesses in
Croydon with large volumes of mail. Many of them are within walking
distance of East Croydon station so, if your destination is in that
area, I would go Uxbridge (Metropolitan) to Baker Street, then Jubilee
to London Bridge, then South Central or Thameslink to East Croydon.
About 90 mins.
