For the first time EVER we didn't rebook on our cruise last week. We decided we wanted to try some new ports so we're looking at Holland America or Princess. Since DCL is our point of reference, we're wondering what people who have sailed on these lines think of them. Our kids will be 5 and 7 and are particularly curious about their kids activities. Plus, we don't want to be nickled and dimed by "extras" that would be complimentary on DCL. Please help!
