Thanks for the replies. I will definately be bringing a sling, but I don't think it'll help too much overall, mainly when we have to get the stroller folded up and I have to keep an eye on both kids, or if I have to feen the baby. To answer the car seat question, my 2 year old will have his own seat, and we will try to see if there is room on the plane to use the baby's, so that'll have to be gate checked. The baby's isn't as much of a problem as far as transporting it because it fits in the stroller seat.
Here is what I have planned so far- We will pack all removable parts of the stroller in a suitcase so they don't get lost/broken and the stroller is quicker/easier to fold, and we will also pack the infant carseat base in a suitcase, leaving the carrier part in the stroller as a travel system.
sharibrat-The backpack case for the other carseat sounds like a great idea, was it expensive? If we can find one and afford it, we'll use that. Next, both kids will be in the stroller and I will be pushing it while my husband pulls the luggage train until it's time to check it. He will be in charge of the big carseat as well. Once the baggage is checked we will only have to worry about the carseat until it's time to fold the stroller down, at which point I will put the baby in the sling and a leash on my 2 year old (yeah yeah, but I don't feel like running around chasing after him) and my husband will again be in charge of the car seats and the carry on. I know that is a lot for him to do all at once, but it will only be while we are in line waiting to board the plane, so he'll live

. All the while, the kids will have been perfectly well behaved, and we will not have run into a single problem (including breaking the stroller down for security- they'll just tell us we look honest and go right through). The flight will go perfectly, not a peep out of either one and we will land in FL and reverse the process, sending one parent to pick up the car with the kids while the other gets the luggage. What a wonderful vacation- easy as pie!
So how does it sound, doable?
ETA- lil.disney.princess- your post just made me laugh! Yes we are from the US, and is it safe to assume you aren't? You speak a bit differently...
