Many people prefer to be waited upon, rather than to serve themselves. Additionally, buffets are not conducive to exchanging information and developing or renewing relationships. While lingering over a meal may be desirable, standing in a long line with 400 other delegates may be perceived to be a waste of time. Finally, buffets are awkward for older people or those with disabilities. Have alternative entrees available.
Many people are on restricted diets.
Restricted diets may require eliminated or reduced amounts of sugar, salt, fat, cholesterol, and meat. Check with your caterer and have an alternative entree available. Provide a space on the registration form for special or restricted diets. Have ample seating available. This is likely due, in part, to the sizable investment volunteers make to attend.
