There is a little “work around” to this, if you don’t mind tying some refundable money for awhile.
The boss and I love the UDP, but we also have a little OCD. We purchase the unlimited plan; we also choose all our dinners, make reservations and pay for the reservations through the CP.
When we boards we go to any restaurant, like you would to make your reservations anyway, have them “transfer” your paid for reservations over to your UDP. The money you paid for the reservations is converted to refundable OBC.
Another money saver is waiting to purchase the UDP until onboard, quite often a great deal can be made.
