A couple things are playing into my response. My twins were my first, and though I was deeply committed to nursing them, I wasn't quite comfortable doing it in public at first. And my husband became nervous if they cried in public, and wanted to run to the car for fear of disturbing others, no matter where we were.
Nursing twins ment sometimes having a bottle in my experience. At first, we had one baby with a bad latch, which took awhile (about a week) to remedy, and during that time there were some bottles. After that was sorted out, we were bottle free when at home, but we used them if we were out, mainly because I couldn't nurse two at the same time without exposing a whole bunch of skin, and needed my pillow, too. So I'd nurse one, and husband would use the bottle for the other. Once they were more moblie it was actually harder, because one would want to nurse if they saw the other one nursing.
Once my boys were 6 months, I was back to work and Husband stayed home, so they had bottles then, too. After that point, however, we didn't use them in public any more. I just nursed.
If you're at all concerned about nipple confusion, the lactation consultant I worked with recommended Haberman Feeders (made by medela), which require more effort in use and therefore reduce the chances of bottle preference. We had no trouble with babies preferring the bottle.
Using bottles may mean that you'll be pumping, too. I found that a pumping schedule of right after each nursing session gave me a decent sized freezer stash and increased my supply.
