I'm one of those moms that has read every book from conception (What to Expect type books) to every age applicable. I heeded advice from just about everyone. One problem with all this... my daughter is a non-conformist. Ask me if I should've bought (or brought to any Disney adventure) about 90% of the items I have for her and the answer is NO! She's never been one for strollers, preferred a child body carrier from the rip. She never sleeps in public (so the idea of napping in the stroller was out). In a nutshell, what I'm trying to say is consider your child's preferences and whatever it'll take to make YOUR life easier. There was only one problem with using a stroller with another child... it was ALWAYS in the way in the room, folded or not, but it was a Peg-Perego fold up- a bit bigger than an umbrella. It was hard to maneuver in the food lines (but KUDOS to staff for ALWAYS helping with the tray) and in the way during buffet meals in the seating areas. Like I stated, this was due, partly to size, partly to how much we really "needed" it for our 8 month old. If you have help to carry the child, think about forgoing the stroller. Heed the advice of the multitude here, as my opinion was just my own experience.
