This question is for those of you who have been on several Disney cruises. All of the shore excursions sound fabulous, but seem a bit pricey. We are a family of four, so the total tab adds up quickly. Have any of you ever tried to do some of these exursions "on your own?" Is it possible to get your own taxi, travel to the same excursion sites, and buy your own admission then? If you tried to do it own your own, is there enough of a savings to make it worth the extra trouble of doing so? I would welcome comments from those of you who have been there before me! thanks
