Slideshow from vacation pics (really another RAW/workflow question)

Here's the issue. I have about 300 vacation pictures in RAW. Right now I am not printing them; I just want to put them together into a slide show to show people. In the past, what I've done is process them all in ACR to JPEGs and then use those for the slide show. I don't want to use the unedited RAW images in the slideshow as some need cropping, sharpening etc. Would it make more sense, to adjust them in ACR and then instead of opening them into PS, just save them as RAW files and then use those? Any other points to consider? Thanks in advance for your thoughts.

If you are going to adjust every image then conversion will be a quick save at the end of each one so a batch will not be necessary. However if you don't and later you want them as JPEG (or another file for that matter) you will have to go through the conversion. I say convert them as you go.
