Went with cowerkers hiking once, we had more than enough to drink with us. What we didn't plan on was a convenient way to carry the bottles, so around half way to our target we had to rest and decide what to do with them. Either leave them there and collect them on the way back or accept that they will be a pain to carry around for the rest of the day. We later found a place where we could drop them off, but getting there was far from just "doing it".
Lesson learned: plan ahead and get something convenient to carry.
