We are travelling with our grandkids 5, 3 and 1 as well as their parents. They will have a stroller for the baby. We want to rent a double stroller for the bigger ones. Since we already have one stroller to put in the car we want to rent at the parks only. We'll do a length of stay rental. Does anyone have any tips/hacks for us? We did this when our kids were little and it worked great, but that was 15 years ago!
