I don’t see why not? People love the Tapu-Tapu when it works, and it’s a genius idea for the restaurants and shops in the park, and for the guests as well.
You don’t have to carry a credit card around, you aren’t standing in a line for hours on end, and, if they choose to do complementary food, you wouldn’t have to carry food vouchers or a wristband that’ll tear and get wet as you explore the park.
