Going to WDW in 30 days for our 1st anniversary trip. I'm in an ECV due to MS, & my DH walks. DH has always carried a backpack, I wear a fanny pack. He's getting older & would rather not carry/wear any bag. I'm trying to decide b/w a small bag in the basket of the ECV or a bag I can hang from the seat back. We travel light: sunscreen, eyeglass cases, his hearing aid case (which I can fit in my fanny pack when his hearing aids are in it), hand sanitizer, xtra socks (in case we get wet), umbrella, rain ponchos. Any recommendations for a bag to hang off the seat? Or any other thoughts/recommendations/things that have worked? Thx
