We took a 10 day road trip back in June when Jevin was 8 months. I brought my big zippered pail liner and we had no stink problems. I have alot of dipes so we only had to wash once. I was planning on going to the laundry mat but I just washed them at my MIL and FIL's (they said I would last, had to prove it! LOL) Having to fly there might make it harder though. We are flying for the weekend in November for a wedding and I am going to do half and half to make my luggage smaller. Cloth while we are there and sposies while traveling.
