I recently used the online form to contact
Disneyland about my experience with the Trams and Security (related incidents, but two different days... I'm hoping to get something typed up at some point about what happened since it involved use of the kennel for a not dog... if I ever stop being lazy... maybe when I'm flying to Florida next week) because I forgot to stop at City Hall before picking up the "troublemaker" (my cat Riley) who was at the heart of the problem from the kennel. I normally prefer to use City Hall because I want to know it was heard then.
That said, I was very surprised at the call I just received this morning apologizing for my experience, promised to forward on the information from the incident for training purposes, and offered compensation in the form of a $20 gift card (the day rate for the kennel). I was
really shocked that they offered anything. I certainly did not expect anything and only wanted to address my concerns about the lack of knowledge of the rules from several CMs, but it was definitely a nice gesture on their part. I did end up accepting it and will just see if there's anything to spoil Riley with since she got the brunt of the stress from each situation.
I've also gotten reentry passes when I've alerted CMs to issues during a ride (TSMM had a screen out) which was 100% unexpected. Ended up giving them to some kids I know that ended up with the blank screen too as we exited the ride.
Anywho, personally I prefer the in person chat if possible. But next best is definitely the online feedback form. Gives one time to compose their thoughts and, as the CM I spoke to this morning told me, allow the person handling the case a couple read throughs to better grasp a situation. The acknowledgment of the issue was a pleasant surprise. I would never expect compensation, though, unless it was an especially troubling experience. A call would be low on my list of wanting to submit feedback.
