I do an entire album for a Disney trip. Anything that I've used more than 6 or so rolls of film gets its own album (ie. usually vacations, but I can bet that someday when my kids get married or whatever, I'll have that many photos!). I use almost all my photos...the only ones I get rid of or don't use are those that are blurry, or didn't turn out for whatever reason (someone walked into the photo or closed their eyes or whatever). Almost all of my photos turn out pretty well...there's usually only one or two in a roll that I don't use.
So anyway, I don't limit. I will add a double page spread in my family album to recognize the trip...but that's more of an overview and place holder.
Typical week long stay...about 50 pages (counting front and back)...my 2 weeks from January will be longer. I think I'll be close to filling my CM album to capacity (60-90 pages..again counting both sides). I had 14 rolls of film.
