If you are coming from the south you will need to negotiate the other two cities first. This is best done by use of the Obwodnica (ring road) which will get you to the centre of Gdynia in about 20 minutes. Gdynia itself is the best laid out of the 3 cities in terms of cars but even parking here is a challenge these days. Head for ul. Świetojanska, which is the city's main street and you will find most hotels and restaurants based around here.
