Thanks for all your replies

I guess it's not going to hurt to sit on a few towels and be prepared JIC! I'm not a control freak so I know that anything can happen and I'm open to it...it's probably more that I feel at ease when I'm prepared so I think I'll do it all anyway. Cheezelmonster - I like your idea of the garbage bag and towels, I might do that for the car too.

Thanks again!
