Some wedding venues will have tables, linens, glassware and dishes that can be rented for the wedding reception. They may also have candles and silk or artificial flowers for centerpieces. This can sometimes be a cost saving feature although it may limit your choices.
If you want to have a quiet and elegant wedding, it is important to check and see if other wedding's will be occurring in the same venue, and what type of entertainment they are planning. In some hotels and larger venues there may be many weddings the same evening, leading to a considerable amount of noise send activity.
