We have been to all of the different character breakfasts. Each one offers something just a little different. Out of your two choices, Storytellers or Goofys, I would put my vote in for Storytellers. It does not have quite as many characters but I preferred it over our last trip to Goofy's for several reasons.
- Atmosphere was much quieter. Goofy's was rather chaotic!
- Food was better. I love their Banana Stuffed French Toast! I was not impressed with our food at Goofy's last time we went.
- You have the option of ordering off the menu. (again, love that Banana Stuffed French Toast!)
- They were better organized. They appeared to have a route that the characters followed which meant that they visit each table. At Goofy's it seems hit or miss.
- Because you do have the option of ordering from the menu, you do not have to worry about missing a character while you are away from the table getting your food at the buffet table.
At Storytellers they did also have a follow the leader game with the park range which was fun for the kids. Goofy's has them get up and do some dancing.
Since you mentioned that you are also going to Ariel's which I assume would be your DD's first choice, you might ask you DS which characters he would prefer seeing and let that help you make the decision.
At Storytellers we saw Chip, Dale, Raffiki, Meeko, Coda and Kenai .
At Goofy's we have seen Goofy, Pluto, Chip, Dale, Cinderella, Mulan, Mary Poppins and Jasmine.
If you might even consider Minnie's, it is also packed with characters and the food is pretty good. Personally, I would choose it over Goofy's. There we have seen Minnie, Pooh, Eeyore, Piglet, Tigger, Chip, Dale, Captain Hook, Fairy Godmother, Brer Bear, Brer Fox.
Of course, then there is also Lilo's over at PP. It's pretty laid back, pretty good food and fewer characters. We only saw Lilo, Stitch and Minnie but it was not crowded and they spent plenty of time with our DD. They also did play games with the kids. The main drawback to this one is that it was a long walk from our hotel on Harbor.
Still, IMHO, my favorite is Storytellers. Aside from Ariel's it is the only other one we will be doing on our trip in November. We will see if my opinion remains the same after our trip!
Good luck making your decision!
