It took me a lot longer, too. I found that some of the questions impossible to answer as there was no answer given that was accurate. For example, I have never sailed Silversea, but had to provide an opinion as the survey did not accept "no answer" without voiding every answer that I had provided on the specific page.
I would love for the people/or person from Regent who are/is going to use the survey for future planning to ask for feedback on the survey. It's been awhile since we sailed on Regent, and I'd love to explain why we have made that choice. Unfortunately, the survey didn't give that option.
