Yup - here come the questions

I am in need of some stroller help. Last trip we brought 2 "higher end" umbrella strollers. They have shocks and the ability to recline, but other than that they are small umbrella strollers. That was with an almost 5 year old and a 2 1/2 year old.

So this trip we will have a turning 7 year old (who never uses a stroller, but I don't know if she might have moments?), a 4 year old (who will need breaks), and a 1 year 7 month old (who will be in a stroller a lot). We do have a double stroller that is front and back, but it is a MONSTER and I think I would rather carry all 3 kids on my back than fold it up and take it on a bus. I have looked into other doubles, but they seems so huge and expensive to boot!

So does anyone have any advice on this subject? Thanks!!
