Put the immovable date first
Write down the mission, family arrival and international departure dates before choosing destinations. Those dates become the frame for the trip; the route should fit inside it rather than compete with it.
Reserve the parts with less flexibility
Machu Picchu entrance availability, trains, hotels and domestic flights may restrict the order. Confirm the essential pieces first, then add day trips and free time around them.
Choose how much Peru fits
A focused Cusco, Sacred Valley and Machu Picchu route works for a short visit. With more time, you can discuss Lima, Ica, Arequipa, Puno or the Amazon. Adding every region is not always the best use of a family week.
Plan for the people, not only the map
A group may include a returned missionary, parents, siblings and grandparents with different energy levels. Ask where you need private transport, hotel flexibility or a slower day instead of applying the same service to every excursion.
Send the complete picture to Deicy
The useful first message includes your fixed date, number of travelers, ages, arrival city, departure city and must-see places. With that information, Deicy can propose a route before the family starts booking disconnected pieces.
