There are a lot of great choices out there. The all-ages resorts that we really liked were Paradisus Riviera Cancun, Azul Sensatori, Azul Beach (for smaller weddings), and Dreams Tulum. We ended up picking The Royal in PDC because my FI and I really like the feel of adults-only which the Royal is, but there is a sister resort right next door and the kiddos can come over for the wedding. It was a tough decision and it's all about compromise, just remember that your wedding will be gorgeous at any of these amazing places!
