I have been a huge fan of the DDP for years, but I wanted to experiment a cash trip. I just got back on 2/19 and I wanted to share my Cash experience.
We were there for 8 nights between Coronado and All Star Movies. The first day we went to LegoLand and the second day we went to SeaWorld. The rest was at Disney.
Even the days we were off property we ate dinner at a Disney restaurant.
We did purchase TIW for $75 with the annual pass discount.
Here are the money results for 2 adults and 2 children.
Disney Dining Plan would have cost us $133.12/night for 8 nights for a total of $1,064.96
Cash for 8 nights was $1,123.27 plus the $75 for a grand total of $1,198.27.
So we went over $133.31 or an extra $16.66/night extra.
First off, our approach was not to save money, but rather eat where we wanted, what we wanted and see how if flushed out.
Snacks - the snack entitlement for us would have been 32 snacks and we wound up eating only 28. The big difference is we were able to get things not covered by the DDP.
For example, we got a $7 souvenir Slushie Cup at LegoLand and one day I did get a large Carmel Latte.
Also for lunches on the DDP we would have been able to get desserts, which on cash we skipped, but we didnt need or miss.
I also do have to say that my son who is 7 is not a big eater and MOST lunches and dinners we did not order him a meal. He shared food with us and his sister. Even when on the DDP we order a meal for him because we are entitled, but it goes uneaten except for the fruit cup. So we did save a little money there. So our personal example may be a little skewed.
A few of the examples of why we are in love with cash will be outlined below.
1. We ate at California Grill which would be considered at Signature and we had a $22 Kazan roll for an appetizer and only 1 dessert.,
2. We ate at Hoop-Dee-Doo Category 1. Another signature on the DDP and you can only get Category 2 or 3.
3. The night we ate at Kouzzina, we got the calamari appetizer and skipped dessert there and walked over to Beaches and Cream and had 2 sundaes over there

Try that on the DDP!
4. We ate lunch one day at Blizzard Beach and instead of a regular soda we got an all day refillable mug.
5. The day we went to SeaWorld we got the all day dining for 2 adults and 1 child.
6. Some lunches instead of sodas we got slushies.
7. Dinner at Rainforest Café we got the volcano for dessert.
8. Dinner at Kona Café both kids got the Kona Cone (Not on the DDP) and we got the pot stickers for an appetizer.
Rounding out the dinners is Ohana, Liberty Tree Tavern and Nine Dragons.
We are planning on going back this summer for 2 weeks, so the TIW will already be paid and will only add to our savings. Granted, every time you take out the room charge, you feel it a little more because it is money you are spending $$$ instead of credits. We tried not to deprive ourselves and I think we did a pretty good job. I really loved the flexibility of ordering appetizers instead of dessert. We also didnt feel like we were loosing money if we didnt order the most expensive thing on the menu and eat two desserts. Plus it wasnt a mad rush of tracking snacks and making sure we used all of them. Plus having to get desserts at lunch so you feel you are not loosing value.
We certainly didnt skimp on our entrees either. At the California Grill, I got the $40 snapper and my DW got the $47 Bison.
And Rainforest Café both our entrees were $30.
Plus the $193 for Hoop-Dee-Doo.
For us, the DDP has lost if value and the menus have suffered for it.
Unless Disney fixes the DDP I dont see us going back.
Very wordy I know, but if anyone has any questions, just ask.
