Wow. Thank you for this thread. I read it all. My Dad rwas recently ill, and now will be need an oxygen tank for most part sof a day however long he lives (which I hope is a really long time!) . He can walk slowly for a few minutes at a time, but the days of him walking WDW for hours is gone. He is having a really hard time with this. He was trying to tell me he thought, if he rested lots, that he could manage without an ECV. "Where to put your tank, Dad?", I asked. "The stroller" was his reply. That is a man having a difficult time accepting his new reality. I want to scream "Your lungs are garbage now!" but I don't. I simply told him what was what and he sort of rolled his eyes. Thank you for helping me understand. I also had no idea that people commented about ECVs riders. That's crazy. That's evil. I never realized. I guess I will paint Dad's tank a nice orange color, and maybe the tubes in his nostril will keep the idiots at bay.
Just as a note, you can often get an oxygen tank holder put on an off-site scooter rental - just inquire at the rental companies, and one should be able to help you - better than balancing it in the stroller or on his lap!
