I have been to most of the Sandals resorts in Jamaica my favorite is Negril. I went to Sandals Whitehouse before the renovation, like it as well but it is a huge resort and long ride from Montego Bay airport. Sandals Royal Plantation was another one we went to, very quiet only 75 total rooms everyone has a butler. I also went to Secrets St. James, amazing resort, technical two side by side resorts, I would base the decision on size of resort and what you are after on the honeymoon. Plantation is the smallest and most secluded for you time. Also very low key and no late night party scene on the resort. Whitehouse/south Coast are the biggest with the other two in between and have a ton of amenities and excursions. One added suggest is to do Club Mobay, it is worth the expedited security coming in and free food and drink going out!
