The usual way to decide length of stay is to count attractions. It misses the time that actually disappears: arrival, check-in, transfers, weather, laundry, a long meal, a child needing a nap, or simply wanting to stay at a beach after you get there. A better trip plan counts usable days and friction.
Two nights is usually one real day
Arrive on day one and leave on day three: unless transport is unusually convenient, the middle day is the only fully usable one. That can be perfect for a focused stop and disappointing for a place you imagined as a restful break.
Three nights changes the psychology
With two full days, you can assign one to the main reason you came and leave the other flexible. That is why three nights works so well for weather-sensitive or experience-heavy places such as Cappadocia.
Four to five nights creates repetition—in a good way
A longer stay lets you return to a beach, restaurant or neighborhood instead of constantly consuming something new. For slow coastal destinations, repetition is often where the holiday feeling begins.
Travel days count as energy, not sightseeing
A two-hour transfer can consume four hours door-to-door after packing, waiting and settling in. Put travel in the itinerary as an activity rather than squeezing a full sightseeing day around it.
Children and groups need margin
The more people involved, the less likely every transition runs at theoretical speed. One main activity per day can produce a better family trip than three reservations everyone reaches tired.
A simple formula
For each base, give one day to the main experience, one block to weather/logistics, and then add days for the pace you actually enjoy. Remove a hotel change before removing the experience that made you want the trip.
A practical final check before you book
Open the itinerary one last time and remove one unnecessary transfer. Check current transport, opening hours and weather-sensitive activities close to departure. A strong holiday plan leaves enough structure to avoid logistical surprises and enough empty space for the destination to change your mind.
