In the age of MagicBands, I'm a little confused by the references to the "convenience" of the DDP. Whether you pay via DDP (with a tip on the credit card linked to your band), or pay the whole shebang by credit card, somebody is swiping your band, bringing you a receipt and having you sign it. What is the inconvenience of foregoing the DDP for these guests (unless they are assuming that the alternative to the DDP is to pay via cash, money order, personal check, or wampum)?
All joking aside, I am asking sincerely: for those who find the DDP a "convenience," what is it about the DDP that is more convenient than simply paying by credit card?
Since my family usually pays by credit card, a dining experience without the DDP is actually MORE convenient and simple for us, in that we don't need to "do the math" to figure out how many "credits" we have left when making ADRs or planning a meal, and don't need to scan the menu for only the DDP-covered items of the greatest value -- we can make ADRs unhampered by whether a restaurant is 1 or 2 "credits" on the DDP, waltz in at the appointed time, and order whatever we actually feel like eating, which nearly always costs us less than we'd have paid for the DDP (and most certainly costs less than the DDP, if we're visiting one or more 2-credit restaurants). Again, to each his own, and clearly the DDP has many supporters, but clearly there's something I'm not "getting" about the "convenience" of the DDP (to which so many refer as their primary reason for purchasing it). What am I missing?
