Tampa girl, those folks are really on a goodbudget . My 11 night European trip was almost $1600 for a couple not counting tips which we paid in cash and private tours that we did on our own. Alaska was high too as we did two flight tours each approximately $150. Tours, photo's, alchol, spa treatments, and extras like casino expenditures really add up. We love wine and I just have to have the DOD! We don't gamble but love spa treatments. You did not mention an itinerary, whether you have toured the area before, or what you like to do, so it is pretty hard to generalize for you. The good news about the S&S card especially for tours which can add up, is if you leave the expense on your credit card, you can pay them off when you get home.
Bon Voyage
