Regarding a couple of trips we had previously booked - a Galapagos cruise over Christmas and some time in Peru and Bolivia:
The Galapagos cruise had a webinar - they were opening the cruise back up again, and the first cruise was the one we were booked on. They detailed their safety and health procedures, which were good. However, it still is a fact that nothing is different about the covid pandemic, no lessening of infections, no vaccine yet, and we are in a high risk group (old). So we decided to cancel, and will probably get most if not all of our deposit back.
For Peru and Bolivia, we are canceling for the same reasons as above, plus both Peru and Bolivia have US travel advisories of Level 4 Do Not Travel by US Dept of State, and a Level 3: COVID-19 Risk Is High (worst rating) by the CDC. This likely will be a credit, so something else we have to fit into our schedule in the future.
The next trip scheduled is to Brazil and Peru for Amazon cruises in May, 2021. We will see what happens to these. And then the next trip booked is August, 2021 to Africa. Perhaps by then we can travel again. Summer 2021 was supposed to be with the grandkids to Europe, but that is not booked.
We tend to book well in advance - partly to ensure we get the tours and accommodations we want (for example, Africa gorilla treks need to be booked at least a year in advance), partly to get discounts, and partly to get cheaper air fares. We now are considering not booking so far in advance for some trips. Especially if we have the flexibility to book alternate destinations (or no destination) if needed.
