Grand Velas Riviera Maya and Hard Rock Hotel Riviera Maya both nail the core math: serious kids' infrastructure so parents actually decompress instead of herding. Grand Velas' 30,000-sqft setup handles the full age spectrum across dedicated zones; Hard Rock's dual-wing model (Heaven for adults, Hacienda for families) is explicit permission structure — you're not negotiating bedtimes in a shared lobby. The rest of the list trades some bells for solid mid-tier value, but if your crew spans multiple ages or you need actual breathing room, the top two earn their price.
