Hi All,
I live in New York and am planning my wedding in Houston next summer (2012) for around 300 people! I have researched and flown out to visit, it seems like, everyone single venue in Houston for an indoor reception but the space has either been too small or too expensive (surprise surprise

Can anyone help or suggest venues please? Some details:
Guests: approx 300
Time of day: evening
Location: in order of preference: Downtown Houston, Sugarland or Richmond
Catering: prefer to do outside catering
Type of venue: a hotel ballroom would be great since I'll have quite a few out of town guests, but a free-standing ballroom near a hotel may work too
Thank you in advance!!!
