I would say if your going to be bringing a young child along then skip Cancun and go to the Mayan Riviera (which is 45mins drive from Cancun airport). Having been to Cancun a few times and the Mayan a few times I can say with assurance that Cancun is MUCH more suited to the young, single, party crowd where as the Mayan is much more laid back, family orientated but still has the jazz of Cancun if you want it. I have stayed in the Iberostar and the old Robinson Club Tulum (change names now I think) in the Mayan and they both were top notch (the Iberostar moreso or course). Great spots for children and adults alike, amazing beaches, great pools and awesome excursions if you're into that type of thing. The cost can be slightly more then Cancun depending on the season, but given the fact your going in late April I would think you would find some nice deals. Hope that helps a little.

Edit: There are alot of good condos for rent in the area as well, look into Condos in or near Playa del Carmen, right in the heart of Mayan and most of the condos are within a gated community which is kind of nice IMO.
