Translation of immortal in Spanish

We were indeed the only ones there so we took our time and enjoyed the moment. A little later we ate lunch which consisted of the snacks we had brought and a coconut. It was only one o'clock.
The next morning we felt much better, but we decided to stay in bed the entire morning to fully recover. We watched some Seinfeld episodes which were running every morning at around 10a.m.
We woke up very early because we wanted to continue to Bariloche in Argentina. We bought some food and sat down by the lake to eat a breakfast sandwich. It was so foggy that we could not see the volcano.
