Romantic resorts for 18 year olds?

For my birthday (I’m turning 19), I really want to go on a couples getaway with my boyfriend but so far I’ve only found one place that allows 18+ to book rooms and that place was the Poconos Palace in Pa. Does anyone know of any romantic spots that will allow my boyfriend and I to book a room at our age? Specifically in the tri-state area (Maryland, New Jersey, Pennsylvania) and possibly Delaware. Any suggestions would be great!

Btw this post is not limited to resorts only, I’m open to any romantic spots such as hotels, motels, etc. let me know!
