Cancun is great, but of course it is Mexico... Been there SB, and Summer break. I can say summer break sucked if you are there for the after the partying action. All the girls are just out of HS and act like they are in HS. I am fresh out of HS so I can say this.. Now Spring Break is great! Also I could say that people up to 30 can go. I remember seeing a few "dads" in CUN and I felt bad for them... But Spring Break is more laxed and fun. For you old people who have some money stay at the Moon Palace, it is AI, and very nice, and of course you can go into town at night.. This year, I am celebrating Spring break in Asia, and then maybe going back to CUN, but I did not plan, so we might take a road trip to Cabo (Yes I said road trip, 16 hour drive from SAN!!!) People do it! Wherever you go have fun!
