Hi. I have a family of four - two adults, two teens, who are going to Alaska the 1st week of July. We were originally on the Tundra Wilderness Tour but then heard from others that you can't get off the tour and hike, so we changed to a shuttle. We signed up for an 8:30 AM shuttle and plan to go to Fish Creek, hike a couple hours or so, and then head back early eve. We are saving lots of money with the change, but it cost us $4 per person to change ($16 total). Now, some friends of ours are saying that we should take an early, early shuttle. My family is saying "no way!" but are willing to take a 7:30 AM shuttle (at the earliest). If we change again, we'll spend another $16 which is not that big a deal in the long run - we still save tons - but is it worth it? Any input would help. Thanks!!
