If it's the full-service Airport Marriott, not the Airport Courtyard by Marriott, you got a good deal. (I'm not saying the Courtyard is bad, but Courtyard is a lower tier brand on the Marriott scale.)
It's been many years since I've been the to the Orlando Airport Marriott, but it was a typical, modern, high-quality Marriott. Given Marriott's high standards, I have no reason to believe that the property would have deteriorated since I was there.
I still remember that dinner was very good. I had a shrimp ceasar salad, and they must have put on a pound of excellent large shrimp with a perfect texture. (I think the kitchen wasn't following the normal preparation instructions, and they gave me far more shrimp than I deserved.)
A quick look at Marriott.com shows that the weekday rate is $149-$179 and even the non-refundable weekend rate is $99 -- so a $60 Priceline rate seems pretty good.
You could have paid less in the Orlando Airport area for a lesser hotel, but it seems like a good idea to stay at a first class hotel before a first class cruise.
