Was actually hoping to take off and land on a grass field since I've never done so before so it'd be something new.. Actually give me a use to practice my soft-field landings
You might want to consider Headcorn. I am training from there at the moment. Grass strip with lots going on (esp at weekends), parachuting, aerobatics etc. It's quite lively for its relative size.
From London you can get a mainline train straight to Headcorn from Charing Cross, Waterloo East or London Bridge stations. The airfield is about a 15-20 minute walk from the station.
Despite the fact that the major cities in Kent are typically overrun with obnoxious teenagers, the Kent countryside is quite impressive from the air. Not called the garden of England for nothing.
If you are interested, drop me a PM and I can get you some contacts.
