Is $489 for all-Inclusive 7Night Cancun Vacation a good deal?

Is $489 for all-Inclusive 7Night Cancun Vacation a good deal? I am thinking about spending a week in Cancun, and travel agency offered me this deal. I dont know what to do, or if this deal I really a good one. So I need someone who was there, or who knows about this things to advice me what to do.

Where you are from? Maybe is a stupid question, but if you are from some big city, I am sure that there are a lot of agencies, with very good deals. Dont hurry. There can be great difference in price between two agencies. So, I suggest you to go to couple agencies. Other thing. Why dont you get numbers from hotels and call them for your-self. I think that they have some discounts, and offers now, because it is season. People there are very nice so they will offer you some solution. But, in my opinion $489 for all-Inclusive 7Night Cancun Vacation is not bad deal.
