I have a client (resort) who wants a virtual tour of the cabins. I have done slideshows with javascript, but I know there are better ways. Does anyone have some suggestions on the best way to make a virtual tour?

If you know how to flash would be the best bet.
You could have a map of the resort, then the visitor could click an area of the map to bring up information and photo slide shows of that area. You could also include a spoken commentary whil they browse. Flash would be the best user experience..
