We were given a certificate for a free cruise for two, as an incentive for purchasing a timeshare with Sedona Pines in Arizona. Spirit Incentives strung us along, asking for a deposit and then asking us to select our destination and three travel dates.
We weren't allowed to "try" to book until 45 days before the earliest date. When we called in, we were told "no availability" even though the cruise line had tons of availability for the location and dates selected. We were told we'd have to accept an alternative itinerary but again there was "no availability" across five months except for one short notice booking leaving from a port 5000 miles away from the one we selected. The date didn't suit, and the one of us on the phone had to decide then and there, take it or leave it.
"No availability" really means they want you to forfeit. The only cruise they offer is likely the cheapest, last minute booking they can find, departing at a time other than the dates you have indicated will work. What a sleazy business model! Don't accept offers that are to be "delivered" by Spirit Incentives.
They don't deliver. Instead, they rip you off.
