I stayed the night of the office Christmas party and shared a lodge with 3 coworkers.
The lodge was lovely, fitted to a very high standard and the bed was the most comfortable bed I've slept with in a long time.
The lodge is basically a three bedroom house with a large open plan kitchen and sitting room, two of the three bedrooms en suite, a downstairs toilet and a main bathroom upstairs. All is very spacious, you'd happily live in one of them.
They are a bit of a trek to the Castle - we ended up driving up and down.
Definitely recommended if you are a big enough party or a family.
