ANother vote for sleeperzz have stayed there and the local pub is great.
and taking in the Northern trails that Devs Mentioned.
around the corner is Moray – with the Monster Trails but as above the local natural stuff is far better.. and still rideable even when wet.
Next stop Aviemore with a mass of beautiful natural stuff Carn ban mor depending on your fitness is a day out in its selfs – then you would have to stop in possibly the best cake shop ever!
then Laggan is on your way home – unless you want to head over to Fort Bill and instead of the Nevis Range ask for local advice (or go to one of the bike shops and get the map) and do some of the natural trails.
I havent even mentioned the south eastern Cairngorms Loch Muick/Glencova area.
As you found last year Scotland aint just the Stanes.
