Jessica,
Last November, I had my wedding reception and dinner on the Radisson grounds and at their restaurant, the Sunset Grill. We also stayed at the Radisson for the honeymoon of course!
I can tell you that Radisson will not give you an upgrade just because you're on your honeymoon.

However, mention the One Cool Honeymoon Program upon check-in and you will get some free stuff! Drink coupons, bottle of champagne delivered to your room, nightly turn-down service, that kind of thing. It's great! We got bottles of champagne wherever we went! You also get other discounts all over the island.
As for partial ocean or ocean view, I personally think it's a waste to pay that much more for the ocean. You can go out to the beach day or night if you want the ocean....partial ocean was just fine for us..totally depends on the person I guess. You will love it no matter what!
