The after party can be just as fun at the reception but grandma the little nephews won’t be there (hopefully). The ceremony and reception was formal and it is good to change things up a big and go informal. An after party of course is optional. Party poopers need not apply. The wedding ceremony and reception flies by and you want to night to never end. It is best to see before hand of local spots close to the venue. Or one can reserve a room at the hotel if you want it to be private. Some folks at the wedding have came far and it would be a joy to spend some more time with them.
Head to Karaoke hang out and act a fool with a microphone. Music helps keep the party going.
Bar or club: Why not keep the dancing going. In other information they mention the couple spotting the tab but others say guests should open up the tab. How bout everyone go Dutch?
A friends pad (hopefully they were invited to the wedding) can be an option. The party can keep on going and can set up spotify list. Food can be preordered and ready to go when everyone arrives. Just be aware of the noise level since you do not want a visit from the police.
(Semi Party) Food trucks or fast food joint: can be miracle workers especially after a night of dancing.
Casino: If one were located close by then it would be a spot to hit up. Casinos are typically open 24 hours a day so you don’t have to worry about your night ending too soon.
