My niece and two friends are coming to Cv in July. Any advice on the best way to get from the airport to cv? I've looked at previous posts and they are all pretty old. Transfer seems to be the most trouble free option but cost seems to be 65 euros plus. Has public transport improved sufficient to make this an option worth considering. Also, they are returning via Lisbon airport. Any thoughts on the best way to get to Lisbon?

A shared shuttle transfer eg holiday taxis, should run out about 20euro each.

LIS by public transport : Uber to Sines station, main line service to Lisbon, metro out to the airport.
