I'm about to go to WDW with my husband, sister, mother, and two children ages 4 and 11months. My mother has stamina issues and will be renting an ECV. I have back issues with nerve pain, but my injury is under control, and I want to try to go without a wheelchair or ECV. That may not be possible, but here is my dilemma. I cannot use a carrier for my 11 month old. My back injury will not allow me to hold her weight even using an Ergo. My husband also cannot use a carrier due to shoulder issues. That leaves only my sister to hold the baby in long lines. I just can't ask her to do that. Would it be possible, do you think, to get a GAC allowing us to use our stroller in lines when the disability is not the child's but the adult who is unable to hold her? We can hold her for brief periods, but if the wait is longer than 10 minutes, we'll be in trouble. If we had the stroller in the line, the baby would be safe, and it would also serve as a sort of walker for me. Having the stroller to lean on actually helps my walking considerably. Do you think that would be possible?
