I don't see why you let a couple of not so great meals and a few CM's texting ruin your vacation? My philosophy on Disney is that I know going in that things are going to be expensive. I'm surprised that you are complaining about parking going up from $10 to $14. Every time I've gone, it's always more than I think it should be, but again, it's a theme park and resort area.
When we lived in Florida, we went to WDW several, several times, and once we took my DH's parents. His dad complained the whole time about what everything cost, and really put a damper on the trip. We told him that things weren't cheap, but he insisted on making side comments about how much everything cost and how hot it was. My solution-DON'T GO TO DISNEY IN THE SUMMER, OR IF AT ALL, FOR THAT MATTER! It will always be overly crowed during the summer months, and that's why we always go during the off season.
As far as CM's texting, well, it seems that it isn't allowed, and if it really "got your goat" as much as you are saying it was, then you should have complained to a manager. Otherwise, why let something like that ruin a vacation that you paid good money for? As I would tell my daughter, be happy you get to go. There are people in this world that will never know what the magic of Disney is all about. Not only that, but there are people who don't have food, clothing, or shelter, and here we are complaining about someone texting?!? I'm preaching to the choir because I have my bouts of it as well. Let's be thankful for what we have and are able to do with the resources we've been blessed with.
