What value do the dining plan vouchers have?
From what I understand is if you don't want anything from the dining plan set menu you can use the voucher as part payment.
Yes, you understood right. They have a value.
Open one of the brochres (depending when are you going to visit) and go do the Dining section. There you find everything - full board, half, prices etc.

So is the monetary value is what you pay for them ie if we go on the half board plus plan the value of the voucher is 33 euros as that is what we would be paying per voucher per night in Feb 15?
