My advice - and what works for me??
Either stay off the Dis, or read 'very' few threads. I have been going to Disney since MK opened in 1971 and it 'sickens' me what people constantly complain and gripe about.
No, Disney isn't perfect and I don't expect it, but we have ALWAYS had a wonderful trip when we go (and we've been many times).
I have never met a 'rude' CM and have never had any problems with guest services (sorry, actually once, but was quickly resolved). I meet CM's with a good attitude and a smile, and that has always been returned. We love the food (oh my, the horrors - and we do know what dining at very nice restaurants are all about - some are 'hit and miss').
So, I ignore all the naysayers/gripers/complainers and enjoy Disney to the fullest. You can 'never' please some people. There's a lot of 'me'ism' these days wherever you go.
Yes, I probably should

about now, but that won't bother me either - I'm just looking forward to my next

vacation.
Hope you have a great first trip, and if you adjust your attitude about listening to all the negativity, you 'will'.
