I personally wouldn't book both if they were my only two sit-downs. While they aren't identical, I find them incredibly similar. They are delicious.
I give a slight edge to Tusker and Cape May is our family's favorite.
I have to agree. Don't do Boma & Tusker, too similar. People call Tusker "Boma lite"
With Rivers of Light opening and Disney price hikes, I expect Tusker will be about $4 or $5 more than Boma for dinner.
Garden Grill would be too sedate and boring for teens.
Biergarten is a lot of fun, but the communal seating can be off-putting if you are not in the mood or expecting it.
Crystal Palace is a beautiful restaurant, and has a lot of wonderful food choices. (Characters happen to be there too, so it can get loud with excited people.)
I would recommend going at lunch, rather than dinner, so it would be less hectic. People on dining plan go for dinner to maximize "value" of the
DDP, so dinners everywhere can get really busy and loud.
Goofey Drool, I like the variety of buffets too. Try a tablespoon of 12 different things. Soups, salads, desserts, many options. I am not a big eater, but like to try a lot of things, rather than eat a large serving of one thing. Your big eating teens should find good choices too.
Have a great trip.
