If you make plans 30+ days in advance - and even then -- just make certain that you understand that circumstances will likely change. Not only scheduling, but hard requirements, e.g. prohibitions on entry as well as soft requirements such as testing, vaccination & quarantine. None of the science people are willing to remotely commit to next January and it is largely the travel industry influencers peddling the "when."
So long as anything you book is fully refundable to a credit card (no "funny money" credits for the future), you are, of course safe.
Bear in mind that the credit analysts following the industry do not expect a significant recovery before 2024. This is, of course, not destination specific. But, it is a consideration before one makes an interest-free loan.
