What do you want your vacation to be?  Sit and relax?  See the sights?  Party all night??  We like Cancun, but we are there to only sit, relax and start drinking margaritas and dirty monkeys when the bar opens at 10.  Good luck in your decision, vacations are good.  Ben

Edit to mention my sister in law is a travel agent and of course we go that way.  She does all of the leg work, we just tell her the dates and she gives us a couple options which we check out on tripadvisor.com.  If there is any problem, she or her agency will take care of it, 24 hrs a day.  You don't get that with an online purchase.
