Anyone who is tempted to redeem any voucher from Spirit Incentives MUST know that the customer will have to accept the company's choice for the time and place of the deal offered.
The operation may not technically qualify as criminal fraud or a scam. You will get a refund of your deposit if you cancel in a timely fashion and are persistent in demanding the refund.
The company is operating a classic "bait and switch" operation. The choices they oblige you to make at certain points in the process are absolute illusions.
When you go to make your reservations, Spirit Incentives will decide what they will offer you, in terms of dates and locations available for your vacation package or cruise, and you are obliged to take it or leave it. The "Reservation" conditions clearly state that you must accept their "offer" of alternate bookings.
If you are willing to accept this, the package may be considered a bargain, although the costs in time and effort are substantial.
