We're willing to pay about $1000 for 3 nights. Why wouldn't you go to Punta Cana? I have been to other places in the Caribeean but I hear lots of good things about PC.What's your budget? But honestly, my advice would be don't go to Punta Cana. I'd personally pick somewhere else in the Caribbean.
The Dreams resort are all nice resorts and on great beach, the food is really good and the drinks are yummy.I stayed at the Barcelo Bavaro Palace Deluxe last year. I would recommend it to a beach and sun lover.
My parents go to Punta Cana once a year, they always stay at the same resort. This is the link for it: http://www.barcelo.com/BarceloHotel...bavaro-palace-deluxe/general-description.aspx
They love it there because its an all-inclusive type of thing.. when you land a driver is right there waiting for you to take you to the resort, the food/drinks menu is very broad and they take care of your needs 24/7.
Hope that helps!
