I don't know anything about Orlando, but I was a Wedding Coordinator at the Treasure Island Wedding Chapel (here in Vegas), so I can tell you our policy.
A lot of people wanted to do a small cocktail reception in their room following the wedding. Each room has a certain number of people allowed in it per the fire code. Nobody, technically, would know if you had more than the 15 people (arbitrary number) allowed in the suite. HOWEVER, room service will not deliver food for larger than the allowed number of people. We had several parties get very angry when they tried to do this without investigating in advance, and room service refused to deliver the food/beverages.
Just a thought.
