How much approx.does it cost to rent out a hotel party room?

check w/ your city hall...the city has rec centers/ club houses..public spaces for rent for good prices. They normally include tables, chairs... In Austin Tx it is $200- $500 for a building overlooking the lake... To rent the botanical gardens for a weddin- $30! Check the city website, go to parks deptartmant, find rentals/ park space...there should be a list w/ prices... AND- they do not require you to 'use our caterer/ bar/ food ...) you get 'exclusive' use of the property for the time you rented it. have fun!
