Islands can "float" as well. Smaller islands used primarily as an aid in cooking or baking can be fitted with wheels and moved around the kitchen as needed to aid in cooking. Whether you consider a floating island will probably depend on what you have installed on the floor now, or plan to install (a soft wood will be nicked and scratched).
Take the opportunity to make your kitchen island mutli-functional because there's lots of options to choose from. Just about any appliance can be built into it including cook tops, under-the-counter refrigerators, sinks, dishwashers and trash compactors. Deep drawers provide a place to store bulky cookware and pullout shelves allow for more easy access.
Space and Design are Important : You need around 3 feet of walking space around the island unit, and you must be sure that the drawers and doors in the cabinets have room to open. If you keep to the 36 inches then you should be OK. The only dimension that must be stated is that of the counter height. Ideally it should be the same as the rest of your kitchen units. If not, then it is not a disaster, but can be disconcerting when you are working on the various surfaces at varying heights.
Besides meal preparation, the kitchen can become a gathering area for family and friends if there is enough space. Since so much happens in the kitchen on a regular basis, getting the layout right is important. The kitchen island can serve as an additional eating area, and food preparation can easily be done there. In a large kitchen, the kitchen island can shorten the distances within the working triangle (sink, refrigerator and range or cooktop) and make it more efficient.
