In Juneau, how possible would be it be to do the Sled Dog Discovery/Musher's Camp (2.5 - 3 hrs) AND the Mendenhall Glacier and Whale Quest (5 - 5.5 hours)? My goal is to see the sled dogs, see the whales, and see the glacier. If not that way... suggestions??? It's me, DH, and DSs (8&9). I guess it's worth noting that we're in port for about 12 hours that day. Thanks for your input!
