need suggestions to simply UX with multiple dropdowns

We are building an app that helps in building itineraries for travelling. In our app a person can make multiple itineraries, each itinerary can have multiple days in it and each day can have multiple places/destinations. Like below

But in order to add a destination to an itinerary there are two choices one is to add it directly using 'Add an item' from above or You can add a destination from its page directly using 'Add destination' model like below

we just want the addition of destination to a day to be easy. But we think ours is too cumbersome. So we require some suggestions and insights.
