I'm a bit late to this party Filobedo!
Highly highly recommend you go and see Seamus at Reboot in Scotland, I still haven't got there but have heard nothing but great things about the course, Seamus knows his stuff as well, used to be part of the Vibram Open team and the course is his baby at Reboot
Lloyd Park in Croydon definitely needs to be played and is accessible by public transport, tram goes to about 200 yards from the first tee - hit them up here
https://www.facebook.com/groups/161149440712718/ it's a much better experience played with local players (navigation can be tough without for a few holes and there are a lot of places to lose discs without locals knowledge) and if you get a chance to play with Rich Wood the chairman take it, he's a great guy.
You have to get yourself up to the Midlands though - an hours scenic train ride from London gets you to either Leamington Spa for Quarry Park or Coventry for Bedworth, these are two must play courses and are within 10 miles of each other, depending when/if you are coming we run a tour series around this area with events every month and some of these are at new or potential new courses, some of the venues so far have been stunning. Hit me up here or at
[email protected] if you are coming and I can let you know what's on. If you get to the Midlands post a message on the facebook groups and someone will be likely to be around to either meet you or give a lift from train stations to the course -

Manchester course at Longford Park is worth a trip as well, fun course and a great local club .
