Thank you everyone for your input. It's encouraging to hear that there are a number of us who remain highly disappointed. Upo n reflection, if we hadn't already booked this trip and confirmed with work & friends - we wouldn't have chosen this cruise. We'd have waited for a better option than Guatelmala.
I have written Olivia twice. I've heard from them once where they stated the decision was with Holland America and it was out of their hands. They did mention that they were sorry for my disappointment. Somehow this doesn't do much of anything.
At the very least it was be nice if the itinerary change would be comparable. That and timely notification with options.
