Build the route
Start with the nights you have. Group places that genuinely work together and protect the time needed to move between them.

A calmer planning order
Make one decision at a time, starting with the route and ending with enough room for the trip to surprise you.
The planning desk
A good itinerary is not the longest list of places. It is a route with sensible travel time, a few priorities, and choices you understand before paying.
Start with the nights you have. Group places that genuinely work together and protect the time needed to move between them.
Compare convenience with actual cost. A pass is useful only when it fits the journeys you will really take.
Lock in limited-entry experiences and high-priority days. Keep ordinary meals and flexible neighborhoods open.
Keep fixed bookings, daily spending, and a real buffer visible in one place so the trip stays comfortable.
