The room wasn't soundproof, and the floor where the guests were staying seemed to be reserved for the bride and groom's family. It was incredibly noisy, with the doorbell constantly ringing and the family joking around, even after midnight, and even in the early morning, it was still noisy. My suggestion: if there are other members of the bridal party or reception, it's best to keep the guests on separate floors so they can rest comfortably.
