Only my experience, others do not have these problems. Bridal parties take over the space entirely. They invite unregistered guests in. The hair person and the nail person and the photographers and the florists and the delivery people for the tuxes are all in the space.
It’s the bride’s ‘special day’ and god help you if you so much as look at the bride crooked, someone will be on your case
They break stuff. They need you to be at their beck and call. They leave a colossal mess.
Mother of bride, stepmother of bride, aunts and cousins of bride all want to come in to ‘help.’ They go thru the kitchen and help themselves to anything not nailed down.
They want breakfast at noon because the wedding isn’t until four but they don’t want to go into town to get lunch after their hair has been done.
I’m sure I have other stories I can’t think of at the moment.
Groups can be a huge source of revenue, just make sure you have a plan in place to deal with them. Unless your place is huge don’t mix groups with couples on vacation. More than likely you’ll never see anyone from the one-time group again. You’ll also never see the couple again, either. If one person in the group has a problem, every person in the group will write a bad review. You can survive one bad review, ten on the same day will kill you.
