We travel out of a single roller bag for a family of 5. Plus we each have a backpack with miscellaneous stuff. We generally leave a little space in the luggage fo whatever we might pick up during our stay. Our kids are 6, 6, and 4 and we're currently on day 8 of 11 in Hawaii. It's been fine, we just do laundry every 2-3 nights.
