No, you can change into something a bit more comfortable. Just don't show in Pajamas.
If your invitation says "and guest" than yes, if not, we would prefer if it was just you.
No, Its really not that far of a drive from the hotel. Please plan rides ahead of time if you plan to be intoxicated at our wedding, we want you all to have fun but to be safe as well. Ubers and Lyfts are cheap in our area.
