I need some help from those who have been before. We have a Graco Duo-Glider stroller that we were planning on bring to Disney. Now we are flying and I don't know if I want the hassle of a double stroller. Our children are 7,5,3,1 and I'll be 16wks pregnant. I've heard the Disney strollers can even fit 3 kids (if the want to squish) and that they are a lot easier to roll. If one of our bigger kids gets in our stroller, it does make it more difficult to push. I've also heard about the hassle it is to take your stroller on the buses. I don't want to cause trouble for everyone, I just don't know if I can justify the money to rent a double for 8 days. My SIL said that Disney cast members seem to help you out with the stroller as long as it's one of theirs. So...I need those with experience to give me some great advice. Thanks-only 5 weeks to go!
