Best 'Bang for your Buck' Use of Dining Credits?

[brertoad]

The reasons not to use credits at these in my opinion would be that they are relatively good bargains, so if you are going to pay OOP for something, these are good ones to pay for. Trail's End for dinner is one of our favorite WDW meals, so this is another case where even though it isn't the most expensive, it is a great way for us to use a TS credit. If we were low on credits though, it is one we'd pay for.

Another good option for 1 credit at AK is Tusker House. We did lunch, but there was a lot of good food and huge variety.

I agree. Trails End and Beaches and Cream are less expensive.
If you want to maximize your DP credits, look for the more expensive dinner buffets, like Boma, Garden Grill, 'Ohana, Akershus, 1900 Park Fare, Biergarten, or some of the more expensive sit-down places, Yak & Yeti, Teppan Edo, Tutto, Chefs de France, Via Napoli, etc.
