Why do so many doctors use drains when drainless Tummy Tucks seem to have no "cons" aside from longer under anesthesia?! (photo)

I'm wondering if I should into other doctors who perform drainless tummy tucks, patients with drainless seem to be up and around and feel great so much sooner. I would love to be able to stand and move around sooner because I have two babies! My doctor says a minimum of 10 days with drains. My surgery is a little over a month and I've put $1000 down but I'm willing to switch based on these answers. Thank you!
