Your excursions will go on your stateroom account, so you can price some of that now off the website. We also put the tips on our stateroom account. (added cash too) Drinks, spa treatments, souvies, photos can be big expenditures. Last 7 nite western we took, four of us had about a $2,800 bill. A little less than I expected, actually. We did excursions at every port, except CC only our teenage son did the teen thing, we rented floats and bikes. We traveled with 2 other families and the buying drinks and smoothies can get a bit out of hand. The really big expense was the shopping on shore, so watch out!
