Should we pack snorkeling gear or rent it there?

Bring your own mask and snorkel if you have them - rental gear is often poor quality. Fins can be rented locally since they take up too much luggage space.

How many swimsuits should each person bring?

3-4 each minimum. The humidity means nothing dries overnight, and you'll be in and out of water multiple times per day. Having dry swimwear is worth the luggage space.

Is it worth packing hiking shoes for cenotes?

Water shoes or sturdy sandals are better. Most cenotes have rocky or slippery entrances, but you're getting wet anyway. Save the luggage space and skip hiking boots.

Can we share one phone charger between us?

Yes, but bring a power bank too. Beach days drain phone batteries fast with photos and GPS use, and power outages are common during storms.

How to Pack as a Couple for Mexico's Caribbean Coast

Pack light with one shared checked bag and two carry-ons. Focus on swimwear, sun protection, and breathable fabrics. Coordinate essentials like chargers and toiletries to avoid duplication. The Caribbean coast is hot and humid year-round with frequent rain showers.

Plan your luggage strategy. Use one checked bag between you (50 lbs max) and each bring a carry-on. This saves baggage fees and forces you to pack efficiently. Designate who carries what in carry-ons - one person takes electronics, the other takes medications and valuables.
Coordinate shared items. Bring one phone charger, one laptop charger, one first aid kit, and one bottle each of shampoo and sunscreen. Split toiletries - one person brings toothpaste and bug spray, the other brings aloe vera and after-sun lotion.
Pack for hot, humid weather. Bring 3-4 swimsuits each, 5-6 lightweight cotton or linen shirts, 2-3 pairs of quick-dry shorts, one light rain jacket each, and flip-flops plus one pair of closed shoes each. Everything should dry quickly.
Prepare for beach and cenote activities. Pack reef-safe sunscreen (required in marine parks), underwater camera or phone case, snorkeling gear if you have it, and water shoes for rocky cenote entrances. Bring a waterproof bag for electronics.
Include evening and cultural site essentials. Pack one nice outfit each for dinners (restaurants require shirts and shoes), light cardigan for over-air-conditioned spaces, and modest clothing for visiting Mayan ruins (covered shoulders and knees required).
