I am planning to have about 200 guests for my wedding. We are on a very limited budget, so I plan on having an early afternoon wedding with an appetizer/cake reception afterwards at the same venue. The reception will end around 5 or 6 pm. I would like to invited the WP, immediate family, and some close out-of-town guests back to our house for dinner afterwards, probably ~20 people total. Would this be rude?
