Thanks to Regent and KLT, we have a lovely shipboard credit for our SF to NYC Panama Canal Cruise on the Mariner. The question is: how can we use it? This cruise doesn't have any Regent Choice excursions that we want (there's only one after Cabo San Lucas, and that's 9 1/2 hours long!), and we're perfectly happy with the wines and booze included in the fare. What does that leave - spa treatments?

On our last Regent Cruise, we were too late to book the spa treatments that Joan wanted, and we ended up losing some of our SBC. (Although not much, since we bought some overpriced goods in the stores.)

Any thoughts?
