Let me pre-empt the skeptics: this was not a mistake fare. It was not a flash sale we got extremely lucky on. This was a deliberate, replicable strategy executed over 8 weeks of planning. Here is every detail of how a family of four — two adults, two kids (7 and 10) — spent 7 nights in Mexico's Riviera Maya for $892 total including flights from Chicago.
The flights: $524 total ($131/person return): Chicago to Cancún on Frontier Airlines during the February school week (not Presidents' Day week, the week before). Frontier's basic fare is genuinely restrictive — no free carry-on bags — but for families who can travel light (we each brought one personal item only), the base fare is unbeatable. Total flight cost: $524 for all four. Key: we booked 9 weeks in advance on a Tuesday evening when Frontier runs its regular sales.
The accommodation: $280 total ($40/night): We stayed at a small family guesthouse in Tulum Pueblo — four blocks from the Tren Maya station — that had a double room with two twin bunk beds, air conditioning, and a shared outdoor kitchen area. $40/night. Reviews were excellent. It was not luxury; it was clean, safe, quiet, and centrally located. We used the saved accommodation budget to do more activities.
Flights are the biggest family travel expense. Aviasales searches 728 agencies at once and surfaces deals most booking sites miss — free to compare.

Breakfast: instant oatmeal and fruit from the supermarket (Chedraui is excellent and cheap). Lunch: local taquerías and mercado food. We found a lunch spot near the market where a full plate — rice, beans, protein, tortillas, agua fresca — cost 60 pesos per person ($3 USD). Dinner was the one meal where we spent slightly more — about $25–30 for the family at a mid-range local restaurant. We ate well. We did not eat at tourist restaurants.
Activities: $0 to $30: Tulum Ruins ($6.50/adult, kids free): $13. Three cenote swims (Gran Cenote at $15/adult, kids cheaper): ~$40. Bacalar lake access: free. Tren Maya day trip to Bacalar and back: $18 for the family. Total activities: $71. Everything on this trip was real, present, and memorable — not resort-manufactured fun. The $892 trip was better than our $3,000 all-inclusive trip two years earlier.
Useful tools for booking this trip: We use Aviasales to compare and book flights, Viator for pre-booked tours and transfers (especially airport shuttles), and GetYourGuide for skip-the-line activity bookings. All three offer free cancellation on most bookings — essential when traveling with kids whose plans change fast.
