We did this for the first time our last trip and really enjoyed it! There are reserved tables so you don't need to worry about lining up tons early. There can be a line for the food at the start but it dies down and they keep replenishing the desserts. We found the food to be quite good - nothing OMG amazing but quite a few good things.
The tables were pretty small though so we were a little crowded with 4 of us at one table. We got up to go to the railing to watch CTM and Wishes. Here are some .gifs I took of our view:
As others have said, you can't really see the parade - you can see the tops of some of the floats and hear the music so you know it is going on, etc., but not a great view.
Prices I saw online are:
Adult: $27.68
Child: $14.90
(though, we just did Dole Whips for dinner that night so we made it work ok

)
