My husbund And I just returned from cancun this past monday . WE also are Delta had no problem non rev seats wide open we also went mid week,. We stayed in cancun it self at Contiental Plaza that we got from www.ID90 for $110 per night AI. This was per room not per person. The serice at this hotel was outstanding. The Hotel itself is a 4 star and we stayed on advice from friends . I think the next time I will go up a notch and stay at the grand Oais or Cancun Palace only for the varitey offered in resturants (ours only had 2 open after 5 for dinner 5 before 5pm)and watersports offered at hotel . Ours had watersports but we had to go to the sister hotel the Serria to use . Not abig deal only 2 hotels down but still. We had a wonderful time and we are more laid back and not into the clubs Cancun is waht you make of it they have something for everyone. We heard about Isle Mujuers once down there. WE go to fish and booked some wonder charters from Carlo's and Charlies dock. But next time we will stay on Isle Mujuers where they are known as a fishing paridise! esp. big game.The beaches are wonderful as the resorts you won't find as many AI but more luxury. below are some helpful links I had .Puerto Isla Mujeres Resort & Yacht Club will pick you up in Cancun and transport you to the island in there private charter boat this is part of your room fee. THey will transport you back and forth if you want to visit Cancun during your stay also.
