It seems one of the local news stations did a report about the organization (Travel Time) some time back, as many people were complaining about the same issue - "buying" trips as incentives for employee programs, and then having to put some kind of a "deposit" on the trips, then having the "trips" mysteriously cancelled and the deposit deemed non-refundable.

You might also check with the Better Business Bureau. If there are multiple complaints, they would be on file with the BBB.
