We will be flying to WDW in November with a 10.5 month old. We are planning to bring our City Mini GT rather than rent. We love the adjustable handle and how easily it pushes. We don't see much reason to pay to rent something we already have and already have at least 1 other trip to WDW being planned for the following year. For those of you who have flown with similar strollers, did you buy the Baby Jogger travel bag to gate check? What were your experiences?
