You will get a link tomorrow, but you can go in through the link you were already sent that had a "more information" link. All you need to do is be logged in and you will be able to look through the tickets once the pre-sale time starts, no passwords.

I got the email today at approx. 7am

I think there would be a legitimate issue if you start sticking vaccinated people next to people who bought socially distanced tickets. In my opinion you would have to also socially distance those people or sardine can them all together away from the socially distanced seats. I am sure a lot of people would be upset if they bought tickets under the notion of being socially distanced and 'safe', but then gameday walk-ups are put directly around them. Vaccinated or not you still have a chance to get or spread it.

There is a fine line to walk until everyone has their fair shot at getting the vaccine if they want it.

I am guessing you can get tickets to any game just fine if you are in right at 10am. Field level (specifically infield) and club infield could be less than desirable for the bigger games though. Season ticket holders really ate into those sections before all the pre-sales even happened.

Of course it also depends on the number of tickets you are after. I will say odd numbers (like 3) seemed to get dramatically better seats in sections. Probably because most are getting 2 or 4 and that is what most season seat accounts probably are. I remember checking a game and it was back of the section on the field level for 2 tickets, but when I changed it to 3 out of curiosity it was within 5 rows of the field.
