The SX260 is a travel zoom compact. It's main advantage is a 20x zoom in a compact package, but it has the same small sensor as most other PnS cameras. If you want a compact camera and don't want to frequently play with settings, it can be a nice DSLr companion (especially if you do not have a 500mm equivilent zoom for your DSLr). I would also check out reviews at DPReview.com and look at the Panasonic ZS15 and ZS20, as well as the Sony HX20/30 (I have the HX30, all 3 makes have different blends of features/performance and another one may fit you better). The SX260 is a quality choice in that market.
But..... Most Disney World photography is wide angle (except the Safari), and there is a category of enthuiast compact point and shoots with bigger sensors (for closer to DSLr quality) and faster lenses (for those difficult dark ride photos and slightly better Bokeh) than the typical small sensor point and shoots. In this range you have the Canon s100/s110, G1X, and for an actual DSLr sensor, the G1X. The best quality you can get in an almost SX260 package is the Sony RX100. If you are wanting the best Disney World camera, I would get an enthuiast camera. Here is a good overview of top choices:
