Travel Budget Planner — illustrative example

INPUT
Two people travel for three nights. Shared hotel USD 90/night; food USD 25/person/day for four days.

RESULT
Hotel: USD 270. Food: USD 200.
Known planning subtotal: USD 470.
Add transport, activities, fees and a separately stated contingency before calling it the trip total.

REVIEW
A travel budget should state the currency, trip length and whether costs are per person or shared. Keep estimates distinct from booked prices and include a contingency explicitly.

This is a teaching example, not a live execution record.
