Diapering- disposables

First off- just wanna say that this might sound odd to most of u but here's the thing. I have ONLY been cloth diapering my LO since her birth. She's 5 months now. I do old school cloth diaper for her which means when she pees, it's wet and I instantly change her, and if her clothes get wet then I change her clothes too. Yes it's a whole load of laundry and work but it's okay.

bcoz of this, I have no experience with disposable diapers that most of the population uses. Could u please explain when do u change those diapers and how often? Is it based on time (say every 2 hours?) or whenever the indicator says it's wet? Or do u peek inside or touch n see if it's soiled and then only change??? Pls enlighten me about disposable diapering as I'm considering it for travel usage.
