I'm considering prolonging my journey for two days in Lisbon. At this stage I would be by myself. It seems a shame to go all the way from Australia, change planes in Lisbon and return without seeing the city. On the other hand perhaps I should return with friends. Any ideas?
I agree with your statement about traveling all the way from Australia and not seeing Lisbon. Being by yourself for two days wouldn’t be a deterrent IMO. There is way more than enough to fill your time and Lisbon has this lovely ambiance that I love.
Spend a bit of time researching the city. It’s also a pretty inexpensive place to spend a couple of days.
