This actually happened to us this Spring. Last December I booked the July 15, 2008 Taste of Tuscany adventure. Over the next few months I intermittently checked back, primarily to find out if more children had signed up for the trip, and each time was not given any total number information. Finally, when I called 90 days prior to make my final payment, after I had given the reservationist the credit card information I asked, "now are you sure this trip is definitely going?". She said oh sure, but she'd just check. She came back and said "well I just checked and this trip has been cancelled, not enough people signed up". Thank goodness I asked! I'm sure they would have called me at some point, but who knows when. To make a long story short, because we had booked all of our travel using mileage awards, it was a mess. I will say the Disney folks tried to help us find an alternate Disney adventure trip and ultimately paid our airline change fee for changing our flights. The only flights available by this time (3 months out) were multiple connections over a 24 hour period and we had to stay 4 days longer than we had planned, because we could not find ANY flights back using mileage until later dates (my husband was not happy missing all that time from work), but at least we were able to make another trip. I don't know how often this happens with Disney, I imagine, not often. It is interesting to note that for 2009 the Taste of Tuscany trip is not offered, it makes me think that the adventure was not so popular. For 2009 itineraries, it looks like they have combined aspects of that trip with the Amalfi Coast and Rome. My advice is to be prepared for the unlikely chance that your trip can (and might) be cancelled. For about a week, while I scambled calling back and forth to Disney and the airlines trying to find alternate dates that would work, it was very stressful. We ended up with a wonderful vacation, but I'd rather not have that concern again.
