When hiking, I have in my rucksack a Platypus pouch, with drinking tube lashed on a shoulder strap. It's so easy to use when walking. Drinking without stopping.
But I also/always have a one liter aluminium container + eventually a standard 1.5l plastic bottle.
The aluminium container is my safety, in case I fall and the plastic bottle and/or Platypus pouch break.

Now, IMHO, the hydration system is really nice when walking. I am not sure it has any advantage, when not on the move....

OTOH and for other purpose, in your situation, I would certainly take my Hennessy Hammock along, in Honduras...
