I tracked every peso for 8 days in Cancún. Hotel Zone prices are EXACTLY 300% higher than downtown - here's my spreadsheet breakdown.

BEER PRICES BY LOCATION:

Hotel Zone bars: 120-150 pesos

Downtown cantinas: 25-35 pesos

OXXO convenience stores: 22 pesos

FOOD COST COMPARISON (per meal):

Hotel Zone lunch: 280-350 pesos

Parque de las Palapas lunch: 65-85 pesos

Hotel Zone dinner: 380-450 pesos

Downtown dinner: 95-140 pesos

TRANSPORTATION TO SAVINGS:

R1 bus from any Hotel Zone stop to Parque de las Palapas: exactly 12 pesos each way. Runs every 8 minutes, 6am-11:30pm. That's 24 pesos roundtrip to save 400+ pesos on meals.

MERCADO 28 SOUVENIR MATH:

Same "I Love Cancún" magnet: 25 pesos vs 100 pesos at hotel shops

Lucha libre masks: 45 pesos vs 180 pesos

T-shirts: 65 pesos vs 250 pesos

MY DAILY BUDGET BREAKDOWN:

Breakfast downtown: 35 pesos

Lunch downtown: 75 pesos

Dinner downtown: 125 pesos

Total food cost: 235 pesos vs 750 pesos in Hotel Zone

Daily savings eating downtown: 515 pesos. Over one week: 3,605 pesos back in your pocket. That's enough for a cenote tour or two extra nights accommodation.
