As you are only there for a day hopefully you will be able to get on most of the major rides but make sure you don't miss out on some of the excellent shows especially the Templo del Fuego attraction, the heat from the fire is unbelievable! Try to get the front seat on Furius Baco if you can and make use of the single rider queue for Hurakan Condor, it usually saves you quite a bit of time (the queue splits as you get closer to the loading area). It can be tiring especially if visiting for multiple days during the summer, prepare for quite a lot of walking as the park is rather large. It is an amazing park and I hope you have a great time!
