I teach college and gave them something similiar to this in my math for Elementary Teachers class. I also included a google maps aspect where they had to approximate the area MK, DL, Hongkong DL or Toykyo DL and Space Mountain. Can't wait to see the results.
My students gave their presentations this week. - most were very good.
They were a family of four, and had $3000 for 5 nights - I did not have them include transportation.
It was interesting to see "non-Disney" people plan...one "family" thought they could do all 4 parks in 2 days and would just spend the rest of the time at the resort (I'm sure the kids would go for that Another family thought they could all share a meal at CRT to make it affordable.
Many researched very well and took advantage of free dining or the gift card.
All families were surprised to find out how much Disney information was out there, how much work it too to plan the trip, and that they could afford it. Most were shocked at the ticket prices but aren't we all???
