Reception only-what to in

Hello! Due to covid my husband and I got married last year, and we are doing a reception only at our original venue this summer. I'm trying to figure out what little things to still include. It will be a regular reception, just without the ceremony. For those that are doing something similar with just a reception this year, or have already done it, are you doing a guest book, favors? Anything you are leaving out or including? Kinda at a loss on the small stuff.

Thanks!
