The first day of the wedding, Dean will be drinking. The second, he will be drunk but not continuing drinking, save for one shot for posterity. Etc.

Dean's also pretty fastidious but not very big on spas or luxury baths, but he'll be pointed in the direction of the spa to relax since he's bad at it.

All for Dean just not knowing how to take flirting or finding a partner in drinking on day one of this wedding!
