Corporate Event Dinner RSVP Site

I need a single-page website that will act as the central hub for an upcoming corporate dinner and drinks evening. The page has to feel fun and vibrant while still staying on-brand, so bright accents, lively typography, and subtle motion effects are welcome as long as readability stays high...
