re family
to the 30 something fellow asking the question--if intending to maybe or for sure have kids, do some trips if possible now, because lets face it, starting a family is a big, full time committment and it wont be a while before you can get away again (most likely anyway) and yes, being a dad or a mom is the most important thing, so yes, family comes first.
Im glad I did a bunch of trips before kids, and then as the years went by, slowly began to be able to do some little ones and then some big ones when family committments were no longer the same.
