We just booked the Central Italy trip for 6/17 through 6/24. Our plan is to take the train from Florence at the end of the ABD, and spend 4 days or so in Rome on our own (our son is looking forward to going to Gladiator training school). So far there are 5, including us (2 adults and 9 year old boy), booked. Now, it is just the 9 month wait, and planning the "on our own" time in Rome.
