Possessives and Attributives

Q. What is the correct punctuation for an event or location for a group? I have the following examples: delegates’ reception, members’ forum, speakers’ room. Is it correct to always use the apostrophe in this way? Thanks.

A. Always? It’s always correct to form the plural possessive with an apostrophe in that way, but it is not always necessary to use the plural possessive in writing about an event or location for a group. An attributive will often do just as well (VIP lounge), in which case you don’t need the apostrophe.
