I don't consider putting photos into an album being 'not scrapped'. They are still there to look at and treasure. How about considering putting a label on each picture - either on top of the acetate, or right on the picture- stating who is in the picture, or the location of the shot? It can be done with a label maker, or printed in your own handwriting on scraps of torn PP, or printed out from the computer in a pretty font. Take the pressure off yourself and enjoy those memories of your trip! just don't leave it so you come back in 10-20 years and say 'now who was that or what was that place again?'
