I can totally relate to what you're saying. We were kinda worried too about eating there because my boys are quite shy, especially my 9yo and frankly, I wasn't too thrilled myself at the concept of riding a wooden horse around a crowded restaurant

So we didn't make a PS even though we were staying at Wilderness Lodge BUT once the boys caught a glimpse of it when we checked in they both wanted to try it. I told them about the antics and they were cautiously excited! So we got a PS (ADR) for July 4th and we had a great time. Our server was very nice, not the most outrageous server, but pleasant. Now I can't stress to you enough just how shy my 9yo is but he had heard about the ketchup thing and I couldn't believe he got the courage up to ask for it!! Well, I guess he also adores ketchup so there was that to consider .......

Here he is, as you can see, delighted with himself!!
The server at the table next to us was sooooooo funny. At one point he came out of the kitchen with a giant dinasour hat on him. Sounds silly but it was very funny as he acted totally non-chalent and almost grumpy (pretend). At one stage, after a very quiet, reserved couple at that table asked for their dessert he shouts out "oh for pity sake, what is wrong with you people, you're sitting 5 feet from the kitchen and you can't get off your butts to get your own dessert. I don't know. I just give up".

He was hilarious. They were cracking up laughing.
We had a great night! Give it a go.
