How often is too often for you?

[Capella]

When I am on a golf holiday, I usually play every day (normally for a week), but I do try to throw in one or two days where I only play 9 holes and I'll happily take a buggy on the days when I play 18 (something I'd never even consider when playing at home). At home I rarely have the chance to play more than two 18 hole rounds on consecutive days.
