We have been doing the same thing re: comparing costs ... and have decided to go with ABD for our 7/25/13 cruise. While I am also figuring a ~$2500 difference, we absolutely loved our ABD tour in 2008 and felt that the experience was really first class and worth the extra money. Your comment re: the Rome day is interesting. Based on my own research, the Vatican is open for free to the public on the last Sunday of the month ... no tour groups ... and they close early that day. So, it will be interesting if the Disney Magic works in the Vatican or if that won't be an option for our cruises (as both itineraries fall on the last Sunday of the month). Hopefully we can see St. Peter's if nothing else!! My family is so excited about the cruise - and now ABD as well - and can't wait til July 2013! Seems so long, but I bet it will be here before I know it!
