Local convention and meeting facilities and service centers are occasionally connected to large nationwide hotel chains. They offer banquet rooms that can provide sit down dinners for a thousand guests more or less. All local convention and meeting facilities and services centers have their own staff of professional cooks, waiters and banquet hall servers. When a local organization or an out of town group hires a local convention and meeting facilities and services center, they charge their members for each event that will be using the convention centers banquet rooms. There is also a charge for attending the convention which usually goes to the owners of the local convention and meeting facilities and services centers for using their conference center to hold their meetings. A successful convention depends on a professionally managed local convention and meeting facilities and services center. These Megaplexes have more than one banquet room and many meeting halls and rooms. If connected to a hotel, they also have many grand foyers to meet and congregate to socialize without the structure of attending a formal banquet or of attending to the group's business concerns at a meeting. Convention organizers like to give their members a chance to meet outside of their formal schedule because if people are too restricted to schedules and events they might think twice about attending another convention. A convention planned by an organization is only as good as the members who pay to attend. Without paying members of groups, most local convention and meeting facilities and services centers will find themselves renting out their space to local flea markets or sales groups. Large convention centers are very expensive commodities and without the necessary funds have to turn to alternative users or worse yet, close down.
