I'm sure it's not everyone's priority, but we like it. DH may say it's a waste, but, he has a good time with the characters too. In their books I put the picture of them with the character across from the autograph, so it's more interesting than a bunch of names.
While waiting our turn we think of what we'll say to the character. Those have been some of our best times, talking to the characters. It's always fun to say something to get a reaction rather than just sign, picture, and thank you. We've learned warrior moves from Mulan, given Flik a rock "pretend it's a seed, okay?", and had to bow to Jafar. It's all part of the fun for us! It's also like a collection, to see how many different ones we can get. This trip's goal will be Marie, Thumper, Silvermist and Fawn!
Now that we're going on our 4th trip, there's a lot of characters we can skip. We'll meet new characters and our favorites. But we've also always managed to do everything else we want, I haven't felt like we wasted time we didn't have.
On the other hand, we don't do pin-trading, so do what you think you'll enjoy.
