Thanks for the replies!
I'm thinking, BelovedHeather, that I might be in the same time frame as you - starting on the 25th... that would allow for the week off (the entire week of the 18th), some preview time, and maybe some tips/hints from others who have jumped right into it. I'd just hate to delay it or miss something by timing a week off at the wrong time - but, you're right, it'll give me time to think about it, preview, set up the workout area, maybe do a workout or two just to give it a whirl and go from there.
Thanks again everyone!
