This list is more or less a variation on those lists. Of course the needs change as the babies get older (for instance, we have to worry about solid food items now) and the list changes depending on the season.
BUT, no matter where you are, clothing items can be hand washed and air dried overnight and dishes can be washed in a condo sink or hotel sink.
If you pack for a week, you can pack for a month. It's the same amount of stuff!
We have rented condos in Florida, Argentina and North Carolina and find this arrangement works best for babies. Hotels are tough as you are all in one room and what do you do when the baby goes to bed at 6pm?? You either sit quietly in the dark or sit on the balcony and get eaten alive by mossies! This way you have a real living arrangement and a real kitchen.
We have never bothered with a 2 bedroom as we have found one bedrooms still fit 2 cribs or pack n plays. However, we are already used to the twins sleeping in the same room with us.
We are also big believers in renting cribs or pack n plays for the condo OR making sure the hotel/guest houses we stay in have these available for our use.
You can use a site like BabiesAway for rentals all across the USA.
Also, if you are traveling within the USA, consider shipping items like diapers, wipes and even baby food to your location from a site such as Amazon or Diapers.com.
This will save you a lot of packing space!
When we fly we keep it to (2) overhead size suitcases, one (big) diaper bag and one backpack PLUS the car seats, snap n go stroller bases (we have 2 singles which we find much easier than the double which we hated) and 2 baby carriers (Ergos, etc).
Obviously since we were driving we had the luxury of packing a few more items, but overall, I find less is more.
I like to be able to make one trip: Wearing the baby/Strolling the baby with a diaper bag on my shoulder (or backpack on my back) and pulling the suitcase. We did this for all air travel and it worked great.
Now that the twins are outgrowing their snap and go car seats, it's going to be a wee bit more complicated for awhile, but we will figure that out as we go and I'll let you know how we do it!
For now, the list. I hope this helps someone on their travels! It's more work with twins for sure, but it can be done and it can be FUN!
