Booking a banquet hall for your wedding party is a very important decision. You must first make sure that you know how many people will be coming to your wedding and then use that information to book a venue that is spacious enough to accommodate everyone comfortably. You should also consider the community where the banquet hall is in and the more "upscale" the community, the better. For example, holding a wedding party in the banquet halls or ballrooms of a fancy hotel in the city is often the ideal place for a wedding party, but you need to work with your budget to find a location.
As far as the interior of the banquet hall is concerned, the best thing you can do is to plan everything out so you know where the food will be served and where guests will be setting, and all of the other important details that must be considered when booking a venue and planning the party. You should also make sure that the area is easily accessible and won't be cluttered with tables and chairs so that everyone can walk freely throughout the banquet hall.
You should also make sure that there is a dance floor or a designated area to dance as often times at wedding parties, the key focus is placed on the food and the dancing so if your venue can accommodate these two aspects, everything else should fall into place. Again, with a banquet hall be sure to book months in advance as often times, the more famous venues (in hotels or other upscale establishments in the area) are booked very early and you do not want to have your wedding approaching without a place to hold it. Hence, I strongly suggest that you book the venue at least three to four months prior to the wedding to insure that you will have a location and set time that will not be assigned to anyone else. Once you complete this task, you can check this item off your to do list which is nice as choosing a location for the wedding and party is often the toughest aspect of planning a wedding.
In short, make sure you find a place that meets all your needs and size requirements and then book that venue well in advance.
If you follow the steps above and complete the arduous task of choosing a venue for you wedding early, a lot of the stress associated with planning a wedding should be eliminated.
