We want everyone to wear what makes them feel their best! Patrick is wearing a tux but you don't need to. A good target would be "semi-formal" or "cocktail". Be comfortable!
YES! There is tons of free parking at Whistle Bear and they allow you keep your car there overnight.
The Sheraton is about 7 minutes away from Whistle Bear. There are lots of Ubers in the area to get you back and forth.
The venue will take your orders night-of and will ensure all dietary restrictions are considered. Don't sweat it!
