I use the Double-Triple (double layout, with 3 decorated pages for each) when I have an event with a LOT of pictures - like my son's football season - but I don't want to make a bunch of extra pages.
Another trick I use to display a lot of pictures without making too many pages is shown here. I get acid free clear envelopes and stack them to make a little flip file.
Close to My Heart now has their own version of this with the new "Flip Flaps". They can flip up and down or sideways and will hold two 4 x 6 pictures.
