Hi! We went in 'o4 when ds was 6 months old. We also used the Playtex Nursers with the disposable liners. That made it all SO easy. We brought along extra liners and nipples, and always carried one of those towlettes that has dishsoap on it. We had one of those divided formula containers, and made enough for 3 bottles for each outing. We brought along bottles aready premeasured with water, and just popped in the formula when we needed it. We have one of those little bags that attaches to the side of the stroller, so we just kept the bottles in there, and didn't mess with needing to bring the huge diaper bag with us (we just brought a smaller, portable bag with diaper supplies). It really wasn't a hassle at all. We did go back to our resort mid-day, so we were able to restock for the next outing.
Have fun!
