Strongly recommended.

Not during this period of time tho.
Around May.

You will have lots of fun visiting clubs and restaurants.
But there are also sites where they are very informative.
You can go to the Mayan Pyramids which are an amazing site to see.

You can go to xcaret which you can swim in an underground river and much more.

xel-ha is kind of like sea world but more space.

Island of Women.

Theres so much to do in Cancun!
