In reply to BigLob:
As for places to stay - traditionally Brits aim for the northeast Pollenca which is certainly a nice area to stay with lots of holiday accommodation. I find it a little far to drive every day since only Creveta is of much interest in that area for accessible routes.
Some people get places on the east coast. Good for deep water soloing and the crags of Magraner, Tiujana and Torre d’en Beu (all good) but a long way on small roads to everywhere else.
Worth considering is excellent accommodation in the central towns of Binissalem, Santa Maria, Alaro or Inca - less touristy and, most importantly, next to the main motorway which cuts down your drive time to climbing significantly every day and you can get pretty much anywhere.
I would avoid Palma and anything in the southwest around Magaluf. Also avoid places north of the mountains like Soller and Valldemossa since you have to pay the tunnel toll twice a day for any crag south of the mountain (which is most of them).
