While I don't mean to be a debbie-downer, I will be realistic.
I worked for the
Disney Store as a Cast Lead for 3 years until 2014, and I have noticed that the level of guest service that we provided at the store vastly outweighed anything I received (or saw others receiving) at the parks, especially up to present. I have been very underwhelmed, and at times frustrated, with the guest service I've received - especially since I understand exactly what expectations are set and should be upheld.
I truly hope that you will have a wonderful trip. I know I was for several years, but as of late had only been able to spend a couple hours in a park at a time, as the experience was becoming less-than-magical. Some of the things I took note of during my trips did make me realize that the quality Disney provides has been on a steady decline. For the first time ever I've noticed how filthy the rides have become, especially in Magic Kingdom. Disney's transportation is not as reliable, and especially in the case of the Monorails, are broken more often than functioning. Most of all, the horrible crowding and subsequent wait times makes it difficult to enjoy a full day at the park without spending most of it standing. (You know it's bad when Animal Kingdom's minimum wait time is 120 minutes and it's a Thursday.)
