Have to agree that i would choose the YC. The resort is very nice. Pros: large rooms compared to the BWI, The best Resort pool on property, proximity to EC, and some of the best restaurants in the area all at the resort.
As the previous poster said, really advertise that you are honeymooners at every chance you have. This will really pay off. Make a few PSs before you go and make sure that they list that you are honeymooners on the PS at every meal. Same goes for your room reservation. Hang in there the discounts usually appear about 3-4 months out.
Perhaps you might want to take Breathless out for a fireworks cruise. Who knows.
