Hi,

We are traveling to Portugal in early September,
planning to go from Lisbon to Portimao by bus.
I see a lot of options like Flixbus, Rede, Renex, Mundial Turismo.
Which of those is a better option (reliable, fast, inexpensive, can have 20kg case)?
Also we will be in Camp Piqueno, so closer to Sete Rios than Oriente station.

Please advise.

TIA,
Oleg.
