Hi
We stayed in Disney 2 weeks over Christmas 2005. We considered the plan but as our kids are 11 and 13 (adult prices) it would have cost us £80 a day.
These are a few examples of the costs that we did pay :-
The first thing we bought was the refillable mugs for just over $12 each. This got us all free soft drinks,tea,coffee and hot chocolate while in the hotel (Pop).
Breakfast cost us approx. $25 at the food court in the Hotel.
Lunch was no more than $45 and sometimes alot less if we had a late breakfast.
The cost of dinner varied and the dearest was Chef Mickey's.A buffet in which we had to pay as adults and the kids eat next to nothing total cost approx. $110.
It is difficult to get some of the more popular resturants booked over the Christmas week so these would need to be booked well in advance (180-90 days).
Whispering Canyons is a favourite of our kids and it costs about $24 per adult. When we went to this resturant I realised that I had done the right thing by not buying the Disney Dining Plan. My kids ordered off the kids meal because that was the type of food they like and we were charged as 2 adults and 2 kids which meant the bill was alot cheaper and this then formed the pattern fot the rest of the holiday.Total cost $65
For us the plan would have meant a timetable to be kept to and more money spent - so it was not for us.
Like Chiara we had a car and eat cheaply off site on occasions.
I hope this is helpful,
Jack
