The Wife and I just came back from a 4 day holiday to a mountain retreat. Fly in by helicopter and allowed 30lbs luggage. (all food, beds, etc. provided) What you wear is not included.
Luggage has weight as I found out, as does clothing so not much weight left over for tripod and cameras. I managed a SWC, three backs, a small metal Gitzo and film. Around my neck I carried my 501CM.
The wife managed a F3, film and a digital thing, then her art supplies.
I would have liked to have taken my camera pack but the thing weighs about 9lbs empty.
Traveling light is tricky.
