We went with another couple last year in February. We had a 9 month old, they had an 11 month old, and we each had an older child as well. We did not have any trouble at all. The babies even napped in their strollers when they got tired. If you plan to fly, you may want to ship diapers, wipes, formula, baby food, etc.. to the hotel in advance, so it will be there waiting for you. Make sure you bring a stroller. You may want to bring a double stroller, because you will be doing alot of walking. (You can rent strollers from Disney, but we wanted our own for the infants.) I would also reccomend staying on property, which makes it easier to go back to your room if necessary. I would be happy to answer any other questions. We had a wonderful time and were glad we went. I am only hoping it will be as easy this year since the baby is now a wild toddler, who never wants to be restrained.
