looking for camera backpack/sling for upcoming vacation

I personally suggest that you look into the Lowepro Fastpack 350 if you want to carry a lot of gear at once. Its a really comfortable bag to carry even with a lot of equipments in it.

I for myself own the Python pack, which gives me enough space for my whole equipment + MacBook Air and iPad 2 and is very nicely padded.
Also it comes with a raincoat, which could be very useful in some occasions.

Thanks everyone. I ended up with a fastpack350 the newer one. I will be able to carry all my gear and my notebook for the plane ride.

Ya I won one of those in a photo competition and used it for almost a year as my daily pack (I take my camera to work and home everyday in it and had room for my lunch and laptop).  Great little pack, I finally got sick of its look and decided to get a timbuktu to replace it, and have been happy with that, but can't wait for my kickstarter bag.  I guess I just felt that the fastback (I actually won both the 250 and the 350) is just to dorky (I had the red one), but very functional indeed.  I also found that having a sling style bag encourages pulling the camera out for shots as I'm walking to work, whereas the backpack style is a bit more work to pull the camera out and thus I found that I would often skip a shot I might have otherwise taken.  Happy shooting.
