The difference between a bid and a full price upgrade, in my case, was around $5k. While I'm willing to throw out a few G's for an upgrade bid to see what sticks, I'm not willing to shell out an additional $5k for a suite. So while the more expensive route may be the safest, Imma bid for that upgrade. I may win, I may lose. Either way I'm on a cruise. And honestly, if I lose, I'll be relieved, because I can use that cash! But couldn't pass up an opportunity to bid.
