Few all-inclusive resorts hand you an entire theme-park collection with your room key, but Hoteles Xcaret does exactly that. The All-Fun Inclusive plan bundles unlimited access to the Grupo Xcaret parks and tours, round-trip airport transfers, meals and drinks into one price — so a Riviera Maya week can mean cenote swims, eco-park days and beach time without a single add-on receipt. Right now the collection's resorts are discounted for winter and spring travel, with savings of up to $600 — including $600 off 3-plus-night stays at La Casa de la Playa and $500 off 4-plus-night stays at Hotel Xcaret Arte. Travel runs December 1 through April 30, and the booking window closes October 8.

I love sending families here because the park access alone usually pays for itself — you're not nickel-and-dimed for excursions all week. If you can travel before the holidays or in the quieter weeks after New Year's, that's where these rates really shine. Tell me your dates and how many rooms you need and I'll pin down which Hoteles Xcaret resort fits your crew, then hold space before the October 8 cutoff.
