DDP doesn't work for us-we like to have more freedom. We love a couple of signature meals, but then we also do other things, as well. We enjoy an Indian restaurant in Kissimmee, and find it's easy to stop at the grocery on our way back....we don't like to pay $25.00 on site for an $6.00 bottle of wine we can get at Publix.
We share an appetizer if we decide to order one, and if we get dessert, we share one, also. Sometimes we eat a light lunch at the parks, or we hop the boat to Gasparillas and have a nice dish of Frozen Yogurt for lunch. Yum!
Between our style of eating, and our preferences, we'd rather shop for a great rental car rate and increase our options. It fits the budget, and us, much better.
