I loved my short visit. It is not a day program when it is open, you just stop and have a look. Some days you can use the big telescope, other days they will set up a smaller one outside for you to look at the sun or a planet. They are very friendly and enthusiastic and very helpful.

During the week they have two different programs--one starts at 5pm, the other at 6pm. The box office closes at 5pm so you will need to purchase your tix earlier in the day if you want to attend the 6pm showing. If you show up at 4:40pm you will be fine. Closed on Sundays. Most cabbies will scratch their heads in wonder if you ask them to take you to the planetarium. Just take any bus or van going to Walmart. You need to walk through the Walmart and Suburbia parking lots. You will easily spot the white dome and cross one more street. Unfortunately, there is very little to do at the planetarium outside of the actual show times. There are some interesting photos and timeline on the walls, but that's it. Sometimes a local school will display its artwork there. The staff puts out some puzzles you can work on -- at most there will be only four folding chairs. There is only AC inside the dome. The restroom facilities are clean and modern. First, each show begins on time with a satellite shot of the Earth and zooms in to Cancun. The live narrator tells you in Spanish what celestial bodies can be seen that particular evening and at what time they will be visible. Note: If you arrive even one minute after the dome doors close, you will not be seated. Entrance to the dome begins approx. ten mins. prior to show time. Next, they project a film which is either a U.S. production dubbed into Spanish or a film made in Spain or Mexico. Even if you have forgotten all your high school Spanish you will enjoy the fascinating programs. One film emphasizes the observational powers of the Mayan civilization. The U.S. film shows what our moon will look like when we return there to colonize it. For 50 pesos per adult you will enjoy an hour's respite from the heat and expand your mind. There are lower entrance fees for children (30 pesos), and (25 pesos) for senior citizens and teachers. At the time of this review, the exchange rate is hovering at 20 pesos per US dollar so you can treat and educate the entire family and not break your travel budget. Before or after the show you can eat at the Walmart food court or buy frosty treats from their refrigerated sections. Note: no food or drinks are allowed in the planetarium show area.
