Pen Y Fan - this would be good, and not
too tough, so a draw to more people. Could even do the whole horseshoe, perhaps without Fan y Big to cut it a bit short if people are worried about time.
Sugar loaf - closer to home, not been there before. Again, not too tough (judging by the height of it?)
The Blorenge - Wales first cache is a motif to go up there, heard it's very nice
Or, more extreme, another chance for those who didn't climb Snowdon in 2012
Although this would discourage those attendees from attending
EDIT TO ADD: Or High Tea - was this discussed last year?
Any more ideas/comments?
