Many hidden costs

I have been given this hotel vouchers and can only advise against it. You have to take at least half board and have to pay themselves for boarding in hotels often. In Hamburg hotels are offered no example. Hamburg is still a popular tourist destination. Our hotel was not bad but not very good either. Very secluded and also it would be more favorable for us if we had booked on the Internet itself without voucher.
This is not a voucher for me.
Saves you rather have the money!
