About 50 Clear Lake area gymnastics and their families planned to take a trip to Orlando in January of 2012.
The Booster Club at Acrosports in Webster raised more than $105,000 and sent it to what they thought was a travel agency named High Mark in north Texas.
Parents said High Mark was highly recommended by a fellow gymnastics parent.
"In July of 2011, parents started asking for confirmation numbers," said Christian Tillinger, president of the club. "Princess dinners and stuff like that... The confirmation numbers were not forth coming. [We] got a little concerned."
Donald Lagrone and Andrea Maxwell were arrested Tuesday and charged with theft from a non-profit.
Investigators said the two sold bogus travel vouchers and airline tickets and collected $300,000 in three months. Prosecutors said there are many more victims.
Booster parents met with investigators from the Harris County District Attorney's office Thursday night.
"I believe in the system and I believe they will get what needs to be done, done," said Tillinger. "The main thing these parents want is not let's get our money back. Let's put these people in jail forever. Honest to God, it's let not let this happen. Let's stop these people so they don't do it to somebody else. We have crying kids."
Investigators said Maxwell is cooperating with the investigation. Both Lagrone and Maxwell were jailed on bonds set at $200,000.
