We just put the diapers in the nearest garbage can. We have a medium sized can next to the upstairs changing table (in our bathroom) and just toss them in either the bathroom garbage or the kitchen garbage when we do a change downstairs (PNP changing table). We've just started to dabble in solids so the poops are just getting stinky. But that's only a couple of diapers a day, so not a big deal to bring out to the garage. Our garbage cans get emptied often enough (every 2, maybe 3 days) that smell hasn't been an issue at all. If you have a bigger diaper pail, stink is more likely to be an issue because the diapers will sit longer.
Oh, and we use all open garbage cans - lids only make the smell worse, IMO.
