Hi Terri!
I also have limited floor space and I have to modify those sashays. I have found that two variations work really well. You can start with the leg abduction (side leg lift) on the step like Cathe does and then, instead of doing the sashay to the back, you can either do a straddle or travel side to side. Repeat twice and you will be in the right position to do the repeater.
I hope this makes sense...
