Congrats on being a MRS, hope your wedding went well! You will love the Grand, it is nothing short of GRAND!! The Grand does not have a night beach party, only a day lunch Jamaican thing, which is a think thursdays. The Suites has a beach party on Saturdays. It is highly recommended you make reservations for the dinners. We had no problem the last time we were there. The first day you arrive, your butler will meet with you and review all this, no need to call in advance. Yes you have access to everything being a Grand guest, so ENJOY!!
