At the beginning of planning a trip, it may happen that the order or duration of the stages is changed several times. Wait until you have made a reservation for an accommodation or an activity before entering the dates in the reservation section. This will minimize the number of unnecessary warnings at the beginning of the planning process. 

Be sure to enter the dates when you make a reservation.

You will then be warned if there are changes in your planning and the dates of a stage do not match the dates of the bookings.
