I'm a bit undecided on the whole bring-a-sleeping-bag-with-me thing.
I'm thinking of just investing in a silk sleeping bag liner and using that when needs be in hostels and so on. The only thing is I will need a bag to do the Inka Trail, and I'm not to sure if renting one is a good idea.
Has anyone done this? I'm not sure I fancy the idea of sleeping in a rental sleeping bag (even with my own liner)....
On the other hand, as I probably wont use the bag very much after the Inka Trail, it seems a bother to drag one around South America with me.
