I'm just brainstorming here. We have 4 kids - a 9 year old with special needs, a 7 year old, a 4 year old and a 2 year old. We're looking into getting an adaptive stroller for the 9 year old, but we're trying to figure out what to do for the other kids. The 2 year old will definitely need a stroller. I had been considering bringing or renting a double stroller. Our current fleet of strollers includes a double stroller, but it's enormous and heavy and not something I'd want to lug around on the buses. Besides, the 4 year old is almost as big as the 7 year old, so even though I haven't tried it, I don't think he would fit comfortably. The more I think about it, the more I think we might be able to get away with just two strollers - the adaptive stroller and a single stroller. The 9 year old won't need the stroller all the time. She can walk, but she just doesn't have the endurance for the amount of walking that will be required. She also gets overwhelmed in crowds, so it will be nice for her to have a little bit of space of her own. I'm sure the 2 year old won't want to be in the stroller all the time either, so I'm wondering if it will work out if we just plan to not go commando and let the middle two kids take a turn in the strollers if they get tired. We went to a much smaller amusement park this summer and we only had the 2 year old in the stroller and the other kids did fine. My major worry about this plan is if they're exhausted at the end of the day. I'm planning to take the Ergo carrier so in a pinch I can wear the 2 year old and have 2 kids in strollers. I think a 7 year old will be fine and the 4 year old probably will be too. We're driving to WDW so I can always put the double stroller in the back of the van so it's there if we decide we need it. Does this sound reasonable? Does it sound like we could get by without a double?
