Hi Tanya,
First, welcome and congratulations!
You'll find lots of great info here. Check out the Sandals posts. Also, if you're looking in Jamaica you might check out the Couples resorts as well, it's the same general concept as Sandals and they have very similar packages, just a different resort. I initially was looking at Sandals but after looking into Couples I changed my mind. Good luck!
Happy planning!
