You're welcome to swing by the Florence's (6 Ashlor Drive Middle Grove, NY 12580) for cocktails after the ceremony before the reception. The reception will take place right in downtown Saratoga which is filled with tons of bars and restaurants! You could grab a drink at Druthers Brewing Company, walk around Congress Park, or just pop into the many shops along Broadway.
Yes! The welcome party is cocktail casual/semi-formal. The ceremony and reception are both cocktail attire.
There is a parking lot at St. Joseph's. Parking at the Canfield Casino is available but limited.
