I hope you enjoy the Alaskan Cruise, we did it in 2006, wonderful. Yes stay away from Covid, travel is risky these days. What happened to your friends happened to my son, wife and two kids, just 3 weeks ago. Tested positive in Athens, refused boarding on the Qatar aircraft to Sydney via Doha. So they headed over to London, for 5 days, quarantined then Copenhagen and Paris for 6 days, back here now.
