We really like CBR. Walks along the "beach," lazing about in hammocks, steel drum music. The only downside is that the beds are doubles not queens like the other mods if that is important to you.
Well, all the moderates have some rooms with a single King sized bed available, usually for 20-30 bucks more a night. If that goes out of your price range I'd personally choose one of the Port Orleans resorts, because even with young love being what it is, if you're sharing a bed, you should at least try to get a queen sized.
But as far as the romantic angle, I'd guess a lot has to do with what you find "romantic." And how much time you'll spend at the resort enjoying the amenities versus enjoying your privacy (mee-yow). Me, I'm not that much of a beach person, and prefer the Jersey Shore and Northeast style of beach versus the Caribbean, which is why I'd opt for POFQ. The grounds are also beautiful. As are the grounds at PO-R but of course that's also a much bigger resort. I'd also give PO-R points for quiet pools. No guarantees they'll stay quiet, but when I've been there, my significant other(s)* and I have managed to get some quality quiet time in those smaller slideless pools without kids cannonballing into them.
Another consideration (which I've been proffering a lot lately) is to see if you can rent DVC points. You'd get accommodations comparable to Disney Deluxe resorts for roughly the price of a moderate. The only downside is no other promotions would apply, like if you were hoping to snag a free dining offer or some other perk. But as a for-example, I looked up points for a room at the Villas @ Animal Kingdom with a Savannah view, and the price for rack rates at Caribbean Resort at the first week in January from this year. If you rented DVD points at around $14 per point, the cost is about the same once you factor in sales/resort taxes (which you wouldn't pay with DVC points). As would a Standard view room at Bay Lake Tower with rented points. Just something to consider...
* I wrote significant other(s) not because I'm some kind of crazy player, but because I've stayed at PO-R 3 times, twice with my first wife (back when it was called Dixie Landings) and once with my current wife. Each time I was situation very close to a quiet pool.
