I appreciate all the replies. I like the idea of testing ourselves online while in our airbnb, pllus it would be less hassle and expensive than going to a Walgreens or CVS in a city we're not familiar with. We already have some Abbott BinaxNOW antigen self tests that we can take on our flight so we could just schedule an online session with either OnPoint or Rapid Test & Trace and our cost would be approximately $30 - $40 total for the two of us. Will Royal Caribbean accept this particular brand and testing method for proof of negative covid test?
