In reply to Barkarzz:
Definitely enough stuff around Dorset that's climbable on a 30m including most of the moderately graded routes at Dancing Ledge. Also Hedbury and the West Quarry at Winspit are fine plus various crags at Portland including the LH end of the Cuttings, The Bower, Lost Valley, Dungecroft Quarry, some of Neddyfields, some of Battleship (Middle Cliff, The Block, Back Cliff RH) and Sharbutts Quarry. However, most of the best easier and moderate routes in the area are longer.
As mentioned by others, Dancing Ledge is a nice spot for a visit but it wouldn't be my top recommendation for someone's first sport climbing in the area. The actual sport routes are OK but not amazing and the easiest lines are 5+ and are fairly stiff fingery climbing.
The well-used lower section with really easy stuff which is used by companies with intro and kids groups isn't actually bolted. It's either trad leading or most commonly top-roping from relatively straightforward anchors, a mixture of drilled threads, bolts and nuts/hexes. It isn't actually in the Rockfax guide but there are topos for it online.
Fingers crossed for decent weather in April wherever you end up.
