Trips built around going out fail for a boring reason: people plan a full sightseeing day as well, and then sleep through both.
Pick cities that start late
Barcelona, Lisbon and Palma all run on a late schedule. Dinner at ten, out at midnight, and nobody thinks that is unusual.
Stay central, but not on the loud street
One or two streets back from the main strip. Close enough to walk home, far enough to sleep. Check reviews specifically for noise.
The clearest sign a city runs on this schedule is what time restaurants fill up on an ordinary weeknight, not just at weekends. A city where locals eat dinner at seven and clear the streets by eleven will fight your plans all week, however good the bars are individually. Checking this before booking, rather than assuming any big European city works the same way, avoids the disappointment of arriving somewhere that quietly shuts down just as the trip is meant to be starting.
A useful trick when comparing listings is to check the map for the nearest venue with outdoor seating or a terrace bar, since these tend to generate more late noise than a normal restaurant. A hotel one street back from a lively square can still be loud if it faces a rooftop bar rather than the square itself. Reviews mentioning specific noise, rather than a generic quiet rating, are the most reliable source before booking.
Plan afternoons, not mornings
Nothing before noon. One thing at three, dinner at nine. That is a realistic shape for this kind of trip.
Know the way back
Night transport, rough taxi fare, and the address written down. This is the least glamorous and most useful thing on the list.
Drinking pace matters more on a trip built around several nights out than on a single big night at home, simply because the days compound. Alternating a heavier night with a lighter one, in the same way an active trip alternates hard and easy days, tends to produce a better run of evenings than trying to match the first night's energy every time.
Booking ahead for one or two venues, rather than deciding on the night, removes the most common source of wasted evenings: queueing outside somewhere full while a perfectly good alternative sits half empty two streets away. This does not need to cover every night, just the one or two places you actually want to see.
Eating around a late schedule
A late dinner changes what the rest of the evening needs to be. Skipping lunch to save room for a ten o'clock dinner tends to backfire, leaving people too hungry to enjoy the earlier part of the evening and too full to enjoy the later part. A proper mid-afternoon meal, eaten around the sightseeing slot rather than instead of it, keeps energy steadier through a long night.
It is also worth booking the one dinner that matters, rather than assuming a table will be free at ten on a Friday in a city that eats late by habit. Everywhere else can be decided on the walk, but a kitchen that stops serving at eleven will not wait for a group that turns up at half past.
In short
Late city, quiet street, afternoon plans only, and a way home. Simple, and it makes the difference between three good nights and one.
