My grandson has outgrown his McClaren Major, so we upgraded him to a Convaid EZ Rider for Disney trips. Disney World is the only place we find we need to have him in a stroller—both because of his tendency to dart off in unexpected directions and because he seems to need a place to retreat to when things get overwhelming. We were considering leaving it with Owners Locker rather than trust the airlines not to wreck it. Has anyone left a special needs wheelchair or stroller with them and can report on their experience?
