I'm traveling with three kids and we've done the Cancun thing a few times. I would like to stay in Akumal, but I'm wondering if there is enough to do for a week and what hotels are family friendly? Some of the hotels that show up in the family category, when I read the reviews, sound like they are adult only? Looking for thoughts/insight on Akumal for a week in March w/ kids 16, 11 & 5-hotels and activities. Thanks!!!
