Beachy head is alluring to me even though I already have SN, though I've been there once already!
You can take a train to Eastbourne from pretty much anywhere in the country.
Partial suspension has simple requirements. You can hang yourself over a door or from the rail in a wardrobe.
Theres a thread here on SS about using the railway, though thats frowned upon and might not be as easy at it first seems.
If you can spend a bit of money the exit bag method is quite effective asI understand, if somewhat complicated to set up.
