Thinking of going up in the summer for a weekend.
Have you looked over there --->>>
on the trails page of the website?
They have this on whinlatter up there:

and for the south loop:

south loop on vimeo[/url]
Theres not a weekends worth at whinlatter itself, half a day to a day depending on how quick you like to take it.
Theres loads of really good riding in the surrounding area (just like pretty much all the lakes) though to fill the rest of your weekend
The book by V graphics is pretty good for the lakes:

Not in stock on the shop part of here at the mo apparantly. Should be avialable in any half decent bike shop in the lakes (its available in others across the country)
Also reviewed in march MBUK!
if your going to the lakes for a weekend then dont bother with the trail centres get on the bridleways and tracks sooooooooooo much more fun!! i recommend walna scar road and.... erm..and pretty much most bridlewys will please you muchly.
Walna Scar Road is very good. The track heading south down into satterthaite? (the place on the West side) is very good too:
