Hilton Portland & Executive Tower, Portland, OR
Voucher for $19 Continental breakfast in either main building or Executive Tower. Full buffet is $23. So, the upcharge remains the same while the base price has gone up (now reflected in the Wiki).
Many Hiltons have an option to apply the value of the Continental to a regular menu item. This did as well, but I was told that it is being discontinued.
As the voucher still listed this in the T&Cs on the back, we were still able to do it.
I was told that the buffet in the main building has more choices in the Executive Tower, but I can't substantiate this as we ate in the Executive Tower both mornings.
Cheers.
