Yep! It's just so convenient. It may actually take slightly more space (if there is air in the bags) but I have each bag labeled with the day of the week. Could do names, but mine will be obvious who they belong to so I just do the day of the week (and actually the #day of my trip). When I put them into a suitcase I'll load all of the Sundays on the bottom, then all of the Saturdays, etc until the first day is on the top!
I pack very similarly (but without the ziplocs) for all trips. Normally I'd do bottoms with shirt, undies, socks inside and then folded together. Stack them into the sets so everyone's clothes for each day is together and pulled out of the suitcase in that order. But for WDW with needed certain shirts on certain days I like to make sure they don't get out of order. But really having the entire outfit together is a huge help. I'll also have one for each of the kids with an extra outfit in my park bag.
I'll have to take a pic. It looks a little massive right now.
If I had jumbo size bags I'm thinking do the same method but depending on just how jumbo everyone's outfit for each day in one. I'd like that too!
