I never do laundry on vacation. Last trip, I took two whisk tablets just in case. Probably will do the same this time. Since we were away from home 13 days, there was a lot of stuff to pack, especially for DD1. We never had to take a stroller or car seat before, plus all the luggage. So we definetly wanted to bring enough, while still limiting luggage and the three us fitting into the midsize rental car with it. Here is how I cut corners, spacewise- I used ziplocs and spacebags, being weary how much my luggage weighed when I was done I took a few extra really big t shirts, to be used for pjs, but could be used during the day if necessary. I took trial size and travel sized toiletries, except for a few things I knew I'd need more of. I packed some snacks in an empty baby wipes container, to keep them from being squished. You'd be surprised how many nutigrain, granola bars, and applesauce tubes fit in there! We only brought 2 days worth of diapers (except the expensive swim ones) and stopped at Publix for that, water, and more snacks. I removed one light outfit (in ziploc) from each person's luggage & put it in the carryon in case luggage was lost. I brought a few sundresses and bike shorts, which are very light and very versatile. The sundresses could be used for a night out, daytime in the parks. I brought one extra sweatshirt and a sweatjacket, along with capris. I wore one pr pants on the plane, and one pr on the plane home. I used really big duffels in place of hard sided luggage, since it's lighter and sometimes you can fit more. Put a large, lightweight, extra empty bag inside your luggage for souveniers. I am usually very unorganized, but not when I pack. I went back to FL to visit a coworker later in the year and she got something out of my duffel for me. She even remarked on how organized it was! I always overpack, but I have realized that the lighter the clothes are, the more you can pack. It will be a challenge for me to pack for the next trip, since we are also bringing DD11 (one more person, luggage, carryon, OY!) HTH!
