I lost my Photo Safari on Friday for the 6 June Cruise - Disney cancelled it (but not all of them - just the one we were on). Anyway, I've spoken to the actual tour operator, plus another one...there is definitely a shortage of guides/etc. going on in Juneau right now it seems.
It’s not just DCL, we’re on a Princess cruise to Alaska this summer and people are losing excursions as vendors have been unable to ramp up their staffing to support the busy summer season. We’ve got a couple backup options planned in each port if any of excursions fall through.
