Cobá offers a few hotels, restaurants, and markets, and food choices abound at stands near the entrance when the archaeological site is open. Prices are refreshingly realistic. A few truly rustic hostelries offer hard mattresses and cold-water showers for budget travelers, and a couple of hotels are on the road to Tulum. Making reservations is difficult, as phone and Internet service is spotty, but it's a good idea to give it a shot during high season.
