Congrats! We will be getting married in Jamaica in December 2011 but are still nailing down the resort.
DeAngelis - I would definitely recommend the Couple Resorts for a honeymoon. We have only been to Couples San Souci in Ocho Rios but it was amazing...by far the best resort ever, and I am saying that when we were rained out for half of it! We are considering Swept Away but it is pricier and San Souci was mind-blowing. I looked at Sandals but I didn't like how big they are bc you just turn into another number. Couples resorts are pretty small (less than 300 rooms) so you tend to see the same other guests so you make friends easily and we aren't super-social by nature. But better than that is the food. Most AIs struggle to provide good food but Couples is really good. And the staff is really great overall. Yes, there were a few that weren't friendly all the time but that was 2 or 3 people out of 100. I also like that they have floats to use in the pool or in the ocean water.
Just look closely, because they aren't all the same. Like only 1 or 2 resorts offer room service, and not all of the rooms have TVs or minibar.
