re: Flying Spirit Airlines

I have an opportunity to fly into Orlando this fall on Spirit Airlines with the wife (no pics) for a reunion. Other option is American Airlines into Tampa (equidistant to our destination), which generally offers nonstops and with how we travel (want assigned seats usually, at least carry-ons, sometimes a check in), the cost for 2 is around $742.

So, I get Spirit is no frills and charges for a variety of selections. They'd offer non stops into Orlando. Having priced it out full, but do you think we'd ultimately save much money? Worth the review? We've never flown Spirit. Thanks.
