We will be taking my 20 month old daughter to Disneyland during spring break and then to the World the week between Christmas and New Year (she will be 2 1/2). Since the parks are going to be extremely busy, I am thinking about buying an ergo (back carrier) for her rather than doing a stroller. I really don't want to try and navigate a stroller through the crowds. She never uses her stroller now. My husband and I are both hikers so we wear her on our backs for all day hikes. She also won't be napping in the park. Any thoughts?
