I always use cheapcaribbean.com
I like to do the same with my kids once a month, I got a weekend in August at Viva Wyndham Tangerine in POP (Friday thru Sunday) at $337, I invited a friend of mine and her 2 boys so this is for 2 rooms, each room with 1 adult and 2 children, Friday thru Sunday. If its just you and your family, I don't see why it wouldn't just be a hundred and some change. To me for a weekend that's good. I also got another deal for a weekend in September, Three hundred and something for 2 rooms( invited LaTeacher and her kids) for Friday thru Subday.
And cheapcaribbean always has "last minute" deals.
