OUR GAURANTEE: Our closest competitor charges 30% MORE for the same tube trips we offer. As a policy, we do not believe in overcharging for our services. We are committed to providing our customers the lowest tube prices on the Guadalupe River. We GAURANTEE that our prices will beat all competitors, and if by a miracle you find a better rate, bring us proof and we will beat it. Not only will we provide you the best rates, but our customer service is unmatched. If you are tired of high prices and long waits, join us at GCC for your next tube trip.
