In reply to Jackt:
The second thing you've got plenty of options in the Cuillin, albeit generally with quite long approaches and a fair bit of commitment. The Cioch via Collie's Route would be a classic choice but is quite complicated to manage, especially the descent. Slightly less complicated is to climb the slab corner at polished Diff, and abseil back down the same way. Window Buttress at VD is quite a short approach by Skye standards, and gives the option of continuing to the In Pin. For bigger days on the summits, traversing Sgurr nan Gillean (up the west ridge, down the 'tourist' route) would be one of the better choices in the hard scrambling/easy climbing bracket. Depends on your beginners, and how confident you are to lead that kind of mountaineering terrain (more complicated than a straight-up pitched climb/scramble).
The first thing is tricky on Skye. Most of the friendlier climbs away from the mountains have some complications. Destitution Point at Neist is pretty good but getting to the bottom is an abseil or a tricky scramble, or if you don't want to walk 25 minutes the 'South of the Steps' area is almost roadside and you can walk to the bottom. I believe a local outdoor centre uses a little roadside buttress on the way down to Staffin slipway, but I never have. There are other little bits and bobs you can kind of make work, but they are a bit limited to recommend.
