Travel tips for the frail elderly

I thought some of you might be interested in what I've learned about traveling with my very mobility-challenged mom. She has a lot of health issues, and can't get around without a walker or travel wheelchair. We've had two children get married - one across the country and one in another state. We brought Grandma with us. I've started a blog to help others. Please let me know if you have any suggestions. Thanks! www.travelwithgrandma.blogspot.com
