in need of a reception hall in md thats not to expensive and you can bring your own caterer.?

Answer 1

The price ends up to be about the same. You have to 1) rent the hall, 2) Rent tables AND chairs 3) have a caterer 4) have a florist 5) have a dj and 6) have a photographer.
If you want to save money go to a reception place that offers packages (some include wedding cake, reception hall, flowers, food, tables and chairs, and even a DJ).
