I would suggest that you can see what are the upcoming wedding shows. View the hotels first before the wedding show.
Once you have decided the hotel, sign it up at the wedding show. You can negotiate for more perks like free flow beer, red wine and wine wine.
You can ask for a free photobooth or upgrade to deluxe menu.
Sometimes you can stand a chance to win the lucky draw too!
You holds more bargaining chip at the wedding show.
