Just want to be ready for getting on buses. DH has used a disney wheelchair past two trips only in parks , of course. This time we are renting off-site, so we will have chair with us all the time.I'm pretty sure DH will sit in chair in line and when bus comes get up to walk onto bus. I know DH is not going to want to the lift thing. Can we just fold up the wheelchair and roll it on the bus like a stroller? Does the driver have to secure it? Do we go thru back door? This is new ground for us.
