Hi Lisa, I was there in March for a wedding and we stayed in just one of the basic rooms which was on the beach side. In terms of sides to pick I would go with the main pool side (the resort is seperated by a road so you need to take the bus across and cannot walk)
At the Airport in Montego Bay there is a currency exchange right after immigration. However, I never bring money when I stay there, I just put everything on my room card and then pay by credit card when I am done. I'd bring some singles for tips (though they say you don't need to tip) I always feel weird not doing so. Also, I don't think you need to bring gifts, I've never heard of anyone doing that.
And the pool bar on the beach side rocks, it's not big but it's a little more private!
