Never been to Cape May but here's my thoughts about Ohana and DHS.
Went to the Ohana breakfast twice in 2009. I loved, loved the food. It is standard breakfast food - eggs, bacon, sausage, mickey waffles, etc.. but so good. The warm breakfast breads are to die for.... one is cinnamon raisin and the other is pineapple-coconut - both were the best breads I've had in my life. Spending time with Mickey, Pluto, Lilo and Stitch was great too. Characters were fun, not in a rush, and came to our table several times. As the previous poster said, family style is more enjoyable because you don't have to get your own food or have to rush back because the characters are coming.... We had this happen at Donald's Safari breakfast at Tusker House -- funny though... our extremely attentive waiter there saw that Goofy was coming, and told me to just sit and relax with my son, that he would go to the buffet and let my wife know.
The boat ride to DHS is slow. I'd pick a different day for DHS when you can get to the park at rope drop when it first opens... or if you are staying on Disney property, then when there is morning extra magic hours. This park gets busy. Get there much later in the morning and Toy Story passes could be gone or for very late in the day. We got there early for extra magic hours and got on right away and quickly racked up fast passes to go 2 more times later in the same day.
