"How about you send the kids and you can do your own thing": Grandparents exclude wheelchair-using son-in-law from their Christmas vacation

It's abundantly clear that we don't live in a particularly accessible world. According to the American's With Disabilities Act, an "accessible" place is

"a site, facility, work environment, service, or program that is easy to approach, enter, operate, participate in, and/or use safely and with dignity by a person with a disability."

Despite the ADA being signed into law in 1990, most buildings and businesses still aren't accessible to wheelchair users. The ADA demands that only government buildings and services be accessible, so that leaves a lot of businesses off the hook for accommodations. Therefore, it's often up to disabled people and their families to ensure that the business they frequent will be accessible to them. 

One family recently found themselves in a predicament after the grandparents decided to exclude their wheelchair-using son-in-law from their Christmas vacation at an inaccessible hotel. When he and his wife pulled out of the trip, the grandparents boldly suggested the parents should send their kids by themselves. What kind of Christmas vacation is this?
