Congratulations to your daughter!!! I am also taking my daughter as an "8th grade Graduation - Congratulations on getting into 1st choice High School" trip. Here in Virginia kids compete for a seat in the High School Specialty Centers. Each HS in our county has a different one with a differnt focus/subject (humanities, math, engineering, comp sci, IB, education, etc). They are like mini private schools within the regular public high schools and are very competitive.
To make the trip affordable this year we are driving. I also looked at YES tickets OR buying 10 day no expire WP&more tickets to use over 3 trips. I ended up buying the 10 day No Expire tickets. With the change in the YES program tickets, I think I chose well. And my teens aren't obligated to attend a class. We are staying at Wyndham Bonnet Creek (my family owns Wyndham) - so much cheaper than onsite and more space. I have been buying a $50 Disney gift card once a month since Dec 2011 so food is covered.
There is another thread about what your 2013 WDW trip will cost. I am shocked at the total trip prices folks are paying, especially those staying in deluxe resorts. $7,000 to $12,000 easily! ALL my trips this summer are costing less than that and we are going to WDW for 8 days (Wyndham Bonnet Creek),
Disneyland for 4 days (Desert Inn or my sister's house, haven't decided yet), Hawaii for 11 days (7 days on Kauai at Westin Princeville Ocean Resort Villas, 4 days on Oahu at Wyndham Waikiki Beachwalk). Total cost for all three trips with airfare, rental car, food, lodging and activities is about $6500! There is no way I'd ever spend $7000 on just WDW, no matter how much I LOVE it.
