Don't really have any great tips, especially since Max and Jack did such a wonderful job with same. But - I can certainly empathize, and feel your pain, especially since I also am from NE NJ, and constantly deal with crowds, pushy and rude people, and a constant "it's all about me, all the time" attitude daily too, which makes it that much harder for me to accept, and deal with, on vacation. Especially when I'm the FIRST one to be kind, courteous, and think about "how the other guy feels" when dealing in crowds. Definitely does not feel good to not have kindness handed back. And I have also been constantly assaulted by growing numbers of people at WDW over my years of going regularly, and their also-growing rude, selfish, and entitled attitudes, I'm very sad to say. And as Iv'e constantly stated here before - no - while it has not stopped me from going (YET!!! - although I have no idea when my next trip will be), it has definitely impacted my enjoyment and "want to go so often" many times, and often left me in a crowded area somewhere, or dealing with some oafish behavior, and wondering "what the HECK am I doing here, and WHY do I love it so much", I'm sorry to say.
Thank you for posting this, and trying to find ways to deal, even though it's not "us" per say, but trying to help "us:" deal with "them" better. Hope I staid all that okay, even though it all made more sense in my head before I posted it. LOL I also do not want this to convey that I have not had great times at WDW, or met any nice and courteous people, so please - no flames. But I also want to firmly state that just in MY experience and opinion - the bad has definitely outweighed the good more times than I can remember. And yes - that makes me incredibly sad - my "happy place" has gotten less o (speaking only for myself) over time.
