A day at the aquarium for $6 for adults and $4 for kids? That’s unheard of in the U.S., but here it’s possible — and there is a lot to do, too. There are hands-on exhibits, as well as a seal show and a bird show. There’s even an opportunity to swim with seals or nurse sharks for just 400 pesos ($20) that kids are sure to get excited about.

However, remind everyone in your party that a day at the aquarium is a chance to work on their Spanish — there is no English translation.
