I don't know if this has been mentioned or if any of you have played the map, but I've played cs_jungle (although I've never seen more than 3 or 4 people playing) that is very similar to the mountain/lodge map you've discussed. It's very creative - custom bridges, a waterfall, many plants - but easy to get lost in. It's a huge hostage rescue map with many paths, and a large valley in the center. There's a lodge type structure in the valley containing the hostages. Could be really fun if a large server was set up. Check it out - haven't searched the maps here for it, but I will.
