Many hotels love to help you celebrate special occasions. Whether it's a birthday, anniversary, or honeymoon, it's worth mentioning to your hotel. Often they might put together something special to help you enjoy your stay. It might be off-putting at first to share your personal business with the hotel, but you never know what you might get in return. You can add a note to your booking or casually mention it at the front desk.
The hotel may offer complimentary services, discounts, or even upgrade your stay. It's always worth trying even if you don't get anything because when the staff know you're celebrating, it'll probably make them more welcoming.
