Yes you can. Here are the major changes for 2008.
For the basic plan, the gratuity is no longer included in the
DDP price, so you have to pay that out of your own pocket. The appetizer is also gone from the TS meals in 2008. As a gesture of sincerity (or something

), Disney reduced the price one dollar, so it's $37.99 per night for adults, and $9.99 per night for kids 3-10. The rest of the plan is the same -- one TS meal, one CS meal, and one snack each day, and you have to purchase the plan for every guest for each day of the reservation, whether everyone is there the whole time or not.
There is also a "deluxe" plan. That plan includes 3 meal credits per night and you can use them however you want (TS, CS, whatever). This plan includes the appetizer for the TS meals, but does not include the gratuity. It also includes a refillable mug for each participant. This plan is $69.99 per adult, and I believe $19.99 per child.
