The only full pre-payment locations are CRT and the three dinner shows (HDDR, SoA, Mickey's BBQ). All 4 of these will "morph" into CC holds if reserved while attached to a confirmed resort reservation that includes an applicable dining plan. Note that failure to adhere to the cancellation policy will result in the full charge being deducted from the CC.
There are a few others that require simple CC holds. In most cases, a smaller fee is assed for failure to meet the cancellation policy ($10-$15) rather than full price.
It's also important to note that there have been many cases where a partial party showing up at either the prepaid or CC held locations have been assesed the cancellation fee for missing members (CG has been an exception to this, because it's not a fixed price type of place). Just something else to be wary of.
