Here’s my story. I was supposed to go on a 10 day trip to the Galapagos with the Galapagos Master on May 18th. The Ecuadorian government decided to close the borders until April 5th, but the Galapagos Master decided to cancel all of their trips until July and offer no refund to anyone. They have a handful of 10 day trips per year, meaning that I will now have to wait for years before I can rebook to use the “credit.” I made all of my payments in good faith and the company is now keeping the money that was supposed to cover the boat, gas, food, staff, not to mention their profit. In addition, the price of the trip increases annually, so in order to rebook a few years from now, I will most likely have to pay even more. It is ridiculous for them to hold $8000 of my money for years!!!!
I am booked on their April 1-11 2021 sailing, think there's still space on that 10 night trip. The jump in price from 2020 to 2021 is not as drastic as 2021 to 2022 (almost $1000). Maybe you can try that one.
I'm running into similar issues with my Raja Ampat liveaboard, they're full on most of my desired dates this and next year, so I'm likely rescheduling to 2022. Have not nailed down the dates yet but I wouldn't mind paying the price adjustment, as it's not like they're full on every trip this/next year, just on my preferred dates
