Another question about excursions. I'm going to be in Juneau, July 3. We want to go on a glacier trek and go whale watching. Which should we do in the morning and which in the afternoon? I've read where some glacier treks using helicopters were cancelled because of rain. These usually seem to be excursions booked for the morning. If Is the weather such that it rains more in the morning or afternoon? If so, would it be a better idea to go whale watching in the morning and book a glacier trek in the afternoon, or does the weather ever clear up?
