Orthoman,
Thank you for the detailed info! We're planning on taking a small-ship cruise, andI understand those don't generally offer as many excursion options. I'll check out Bear Creek Outfitters - I'd guess that they'd be amenable to independent bookings if they have openings after those of the main cruise lines.
I understand what you mean about the humpies. It'd be new to us too, and like you we'd enjoy it for a half-day trip.
Cheers,
Jeff
