For a day in a package, you can add more than one location. This makes sense, when you have more than one activity in one day, for example when you have a city tour in the morning, and a wine tour in the afternoon. When you add the locations for the day, add them in the order in which you will visit them. The last location you add will always be the one in which you choose your accommodations for the night.
If you have more than one activity during the day but in the same place, you will have to add the same location twice, so that our system will allow you to add two default activities in one day.
Note that you don´t have to add a location twice, if you simply want to add an alternative for an activity in one place.
