I couldn't have survived without a triple stroller. We used
the Triple Decker stroller with the snap-in carseats for the
first year, and then converted it to take the Bell bicycle
seats once the kids outgrew their infant seats. 

Our kids are turning 2 soon, and we've racked up crazy
mileage in the stroller. It's an inline stroller, and it
folds fairly easily to pack into the minivan, so it's been
very convenient to take on road trips. It is also our
preferred stroller to take on walks around the neighborhood.
We've walked off-road with it, hiking on trails, and my
husband has even run a road race with the kids, pushing it
all the way. (What a sight that was!)

You could probably get a double and use a Bjorn in the
beginning, but it will be nice to have a triplet stroller for
when they're older. Also, because you'll have 2 others to care
for while one is in the Bjorn, it doesn't make it as
convenient as with a singleton. If the baby in the Bjorn is
sleeping, and you want to soothe one of the others, it'll be
a bit awkward to pick the other child(ren) up.
