>>On average, we tend to spend about $1000-$1500/week for the both of us including airfares.
Without wishing away the time with our children when they are small, I do look forward to the day when I can buy just two airline tickets, rent a small car and stay in a hotel room (instead of a big house) when the children are all old enough to leave alone and thus travel more frequently, for less money and more spur-of-the-moment.
Travelling with a family of 6 (with all kids under 10) is a major undertaking....
