This package was a great deal for my wife, son, and I in Cancun last year. The CasaMagna in Cancun had 5 dining spots on site as well as a swim up bar. The only things you had to pay for with this were: premium cuts of steak (only one on the menu), room service, and champagne, and full bottles of wine.
Our 6 y/o son was able to go to the kids club free, which usually costs $30-40 per day as well.
Overall, this was an amazing deal. My math looks like this:
Breakfast daily x 2 adults= $30
Breakfast daily x 1 child= $10
Lunch daily x 2 adults= $40
Lunch daily x 1 child= $15
Dinner x 3 people= $100
8 misc. drinks per day soda/alcohol $50
Kids club daily= $30
Total=$275 x 7 days= $1925.00
The value is truely in the eye of the beholder. For this beholder the $1925.00 may not have been as readily available and not having to fork out that kind of cash was great, especially when my employer paid for the nights that earned my points!
