I just got back from there & married on 9/10/11!
Monday nights are the "White Party" they have a Best Dressed Couple contest
Friday is The Beach Bash, with fire eaters & dancers. You want to wear Jamaican colors (black,red,yellow, green)
Saturday night they have live bands
definatly want to make reservations asap for the French restaurant-Le Jardinere, The Thai restarant & I highly suggest trying 2 restaurants at the Sandals Montego Bay. (Tokyo Joes right before sunset! & The Italian restaurant)
The BEST money we spent the entire trip was to do an excursion to Mystic Mountain. They have a Sky Lift, Zip Lining, Bobsledding & an infinity pool that is 1000 feet above the island looking down at the ocean, beach & gorgeous flowers! Seriously the prettiest sight I ever saw! We did not zipline so it was $120 for sky lift & bobsledding with free pool & waterslide. if you zipline its $160. Then you can go to Dunn's River Falls to climb a waterfall for an extra $15-Which is a MUST!!!! Bring a water camera to take breathtaking pics!!!! We went on a Thursday, left at 9:30am & got back at 5:30pm. They stop at Sandals Ocho Rios to let you have free lunch & drinks around 2pm.
Please let me know if you have ANY questions regarding Royal Caribbean! I have lots of pics too!
