Lisbon for groups above 80 people and for teams flying in from several countries, Porto below 60 people and when budget comes first. The difference comes down to two things: the number of direct flights and hotel capacity.
We organise in both cities. This comparison also sets out the cases where we recommend Porto, because they exist.
Flights, the real starting criterion
This is what decides most often, and what people think about last.
Lisbon has direct links to almost every European capital, with several frequencies a day from Paris, Madrid, London and Frankfurt. Porto is well connected, but with fewer frequencies and more connections depending on the departure city.
For a group leaving from one place, the difference is small. For a group converging from four countries on the same morning it becomes structural: in Lisbon you stage arrivals across one morning, in Porto you sometimes spread them across the day.
Hotel capacity
Lisbon absorbs a group of 200 in a single property without difficulty. Porto forces you to split across two or three hotels sooner, which complicates logistics and dilutes the group effect.
Below 60 participants the question does not arise. Above 100 it arises seriously.
Budget
Porto is cheaper than Lisbon, on accommodation as on catering, at equivalent standard. The gap is real.
But it is partly clawed back on flights, when connections force pricier tickets or an extra night. The calculation is done file by file, not city by city.
Venues and activities
Lisbon has the Tagus, which opens up regattas, private cruises and rooftops over the river. It also has Sintra and Cascais thirty minutes away, and the ocean at Carcavelos for surfing.
Porto has the Douro, and that is a genuine asset: the cellars of Vila Nova de Gaia and the quintas of the valley offer a setting Lisbon does not have. For a seminar built around tasting, food and wine heritage, Porto is ahead.
Weather
Porto gets more rain than Lisbon, particularly from November to March. On a winter seminar with outdoor activities planned, that counts. From May to September the gap becomes negligible.
So which one?
Our rule, after several years in both cities:
Porto if the group is under 60 people, leaves from a single country, and budget is the number one constraint. Or if the theme of the seminar is wine and food.
Lisbon if the group is above 80 people, converges from several countries, or if the programme needs a substantial plenary and an evening in an exceptional venue.
In between, at 60 or 70 people from a single country, both stand up. We cost both when there is genuine doubt, it costs nothing extra.

Frequently asked questions
Can we combine Lisbon and Porto in one trip?
Yes, but over five days minimum. On three days the train or the internal flight eats too much useful time.
How long does it take to get from Lisbon to Porto?
About 3 hours by direct train, slightly less by air once transfers and check-in are counted.
Is Porto suitable for a 200-person convention?
It is possible, but accommodation will be split across several hotels. At that size we recommend Lisbon.
