Doing a SB cruise in late Aug (two couples & young teenager). Am thinking of renting car and taking drive into Yukon from Skagway and trying to decide best way to utilize the 10 hours in Juneau -- can we do Harv & Marv and still get to glacier? Ketchikan seems like it might be more of a city tour than an excursion. We're first timers, so all advice welcome! Thanks
