Well, it depends on what kind of person he is. I personally like rides more than shows, but I do enjoy going to alot of disney shows aswell. But my friend enjoys walking around, shopping and going to shows more than going on the rides. I love all of the rides at disney even though there aren't that many. for the shows I like:
Beauty and The Beast at MGM
Indiana Jones at MGM
Wishes fireworks at MK
Illuminations fireworks at epcot
And sometimes I like special shows that they have at only one time of the year like around Christmas or Halloween.
You also should try and watch the little skits they do in Epcot, there is one in every country and even in the future parts of epcot.
For restaurants again it depends on th person and what you are in the mood for, My favorites are:
1. 50s prime time at MGM (its like a sit down meal with your extended family, your "aunts", "Uncles", and "cousins" serve you and you get in trouble if you have ad table manners and don't finish your food, it is deffinately my favorite at disney)
2. Chef Mickey's at the Contemporary resort (it is a character meal, but very good it is also a buffet)
3. Sci Fi Cafe at MGM (it's like a drive in movie. You sit in a car that is really a table and you watch an old black and white movie while you eat.)
4. 'Ohana at the Polynesian hotel (I had dinner there and they give you alot of choices to eat and for younger kids or even if you want to join in, there are game that you can play. But the food was excilent)
5. Spirit of Aloha at the Polynesian hotel ( this is a dinner show. The show is fantastic and the food is good, but it takes a while for the food to get to the table)
6. The rain forest cafe in Animal kingdom and down town disney( It feels like you are eating in a rain forest and every once in a while there is a "thunderstorm" again the food takes awhile to get to the table and there is normally a pretty long wait to get inside but you can make reservations. You might actually want to make reservations for most of the sit down meals)
7.Teppanyaki in Japan at epcot( this is a Japanese restuarant and they litterally cook your food on your table. its really nice and good food too.)
8.Liberty Tree Tavern at MK( it is a sit down meal and it is american food in an 18th century themed INN, the food is normally like a thanksgiving dinner, and they have the BEST mustard ever!!! and you can only get that mustard at that restuarant, they don't sell it anywhere.)
9. there are a lot of fast food places. they are everywhere, in every park even at the hotels. the food courts at the disney resort hotels are cheap and hsve good food aswell.
I hope this helped and if you have any more questions just PM me and i will be happy to answer them. Oh and I am 15, but I have been to disney about 11 or 12 times and I am going again in august for my 16th birthday. have fun on your trip!!!!!
