I did the trail last July and the rangers always tell people that it's going to take longer than expected because this trail is gaper central. Don't get me wrong, there are difficult spots, the Golden Stairs is more a pain in the ass than actually really difficult. With a full pack on your back it just takes awhile to climb over refrigerator size boulders on a fairly steep pitch, but it's not that long of a stretch. I did it in five days cause I was with older people who hadn't hiked in 20 years, but easily could've done it in four and I didn't go beyond Bennett - took the train back to Skagway. Take every piece of rain gear you've got, you will be wet, you will sleep in a puddle at least one night and your stuff will never dry, it's SE Alaska. There's no time to go when you can garuntee good weather. It is fun, though and more scenic on the BC side.
