CN - Daily Mail on what guests complain about when it comes to weddings. Cash bars, long gaps, evening guests (tiered guests), etc. basically most everything we say on here.
What differentiates an average host and a great host is anticipating unexpressed needs and wants of their guests. Just because the want/need is not expressed, doesn't mean it wouldn't be appreciated.
