Last time we took my brother to DL he was able to do some walking, so we had rented a wheelchair while in the parks. Well this time he's going to need a wheelchair full time for both inside and outside the parks. We've gotten a light weight one that's gonna fit in the van for the drive down. Like some of the stories I've heard about strollers just "walking" away while everyone was on rides, I'm concerned someone will take the wheelchair while were on a ride. My Mom wants to pad lock it to something, I'm not even sure they'd allow that! Not to mention it would be a pain in the butt. But if it's the only way to make sure we still have a wheel chair I'm considering it. Anyone else ever have someone there with their own wheel chair, with this concern? Hate to even think someone could even do that, but honestly I can see some people thinking it would be fun so they could get ahead of people in line.
