My daughter is having a candy buffet at her wedding....but we've never actually been to a wedding that has had one.....how do we handle serving from the candy buffet?......like what time....after dinner??.....and do we have to keep it closed off somehow until then?...do we dismiss a table at a time?....or leave it "open" all the time....from the beginning of the reception?....just not sure on how this candy buffet thing works. Thanks for your comments.
