return to, the commitment of alpine style is greater than expedition style in terms of the choice to ascend or descend. A climbing group caught at a point where conditions do not allow further ascent must consider other options such as an unplanned bivouac (perhaps without the appropriate gear), rappels (leaving multiple pieces of protection behind), or moving to another route from their current position (perhaps without adequate knowledge of an alternative route). However, alpine style often is cheaper and faster for those on a budget, as alpine style climbing typically involves less equipment, and eliminates the need to hire porters.
