I find it interesting that your daughter is studying Entertainment Events management and does not want to deal with the guests. She may want to change career paths before she gets too far into it. Also, and it's just my opinion, that with two cases of food poisoning and so many issues with the food at Disney, the problem may be elsewhere. I, for one, think that Disney has raised their game in the area of food service, not only at the restaurants, but also at the various stands throughout the parks.
I know I will get slammed for this post, but there may be a reason the son and husband want to be elsewhere!
