It’s right in the brochure: Any cancellation of reservation, deposit will be moved to future trip.
They’re holding deposits to be applied to a future trip. Whether they fix their cabins while the border is closed is what’s completely immaterial. I paid for a week’s trip well in advance for June 2020 and I’m pretty sure I won’t be using it this year, either, but I can guarantee they’ll keep rolling it over for me until I get there. I’m glad they didn’t put it in a coffee can and bury it behind the fish house, too. It never even occurred to me to ask for my money back. I’ll just take two trips there next year, or maybe even three.
