Its amaze but waer light layers coupons I'm not sure about but bring an poncho because of the water that drips from the ceiling but don't worry its natural water and probably the freshest water you'll get and bring a camera or phone cause you will want to take pics there is also a place were they take a photo of you so try to look nice because you will want that photo
Safari may be better option. Less expensive and same location. Kids will love
Groupon
It was cheaper buying online, but it is still pretty expensive. It is worth it. In my opinion.
You can purchase ahead of time at a lower price, but they make you choose the time you want. You can also get one of those travel booklets from San Antonio hotels that have discounts.
You can save money by just not going, but that's no fun! I'd check groupon and or call for specials on rates. I believe they can help with special needs children as well.
Tickets are a little less expensive if purchased a few days before. There are a few other caverns that are less expensive.
