It took two days to install the irrigation on one hole in the middle of winter. Less disruption than you would expect.I'm definitely not an expert in these things, but that sounds much more expensive overall than installing it all in one go. Also more disruptive.
Cost, I’m not sure but the people brought in to help are very efficient. We already have full irrigation on greens and tees so not starting from scratch.
