Ensuring the best guest experience:
Hospitality is key. Guests want to feel important and well taken care of. Their experience and comfort level is paramount to any successful event. A few examples of things to consider:
Staffing - is the event staffed properly so there are no lines at the coat check or bars? Sometimes adding even 1-2 staff members in these cases can make all the difference.
Catering - is there enough variety for guests who have food restrictions (such as vegetarians, vegans, gluten free, etc.)?
Seating - if it is a dinner party, I always think it's very gracious to assign seats - to think about who guests will be near and what their surroundings are. For example, seat guests together who have similar interests so they can engage in a good conversation; or put older guests near the dance floor so they feel like their in the action, even if they stay seated for the night.
