A 3 feet separation in line would still be useful. Pre-covid, a lot of times people behind you in line were right on top of you! At least this way you can get a little space. A foot or two is better then before when you had people bumping into you.
and people who got upset if you had any gap between you and the party in front of you. Like moving up 2 feet is going to get you on a ride faster when we are still 20 minutes back in line
