EDIT: Ok, so I took what you said and ran with it. Now I am not sure the B&W's are going to be to your liking now, but your talk about too much white got me thinking. I went back and used Shadow/Highlight to get the detail back in the snow and add some much needed contrast. The snow isn't just a solid blanket of white anymore but now has some texture. Depending on the image, I also used Brightness/Contrast to bump up the contrast a bit more. I like what I see, but the eye of the artist is always blind just after making changes, so let me know if these are an improvement or a step back.
Good luck. Even with a point and shoot I am sure you will be able to snag some awesome photos.I'm going to Egypt but I am not bringing my SLR. I'm bringing my girlfriend's small portable so I'm not sure how my pictures will turn out. I would normally bring my SLR but I'm going to be roaming and touring so much I'm afraid I would damage it (or it would be too much to lug around). I just want something that fits in my pocket.
