Yes, the Portland presale was botched.  Click not the ADA link above to switch to non-ADA seats.  Orch C row G off to the side was best I found.  Diamond tickets do not tell you exact seat location.  For $500/pair I want to know exactly what I'm buying.  I did  not purchase for this reason.  Not a great presale.  

Portland Presale is only showing ADA and Premium Package options. 

If you buy Diamonds, will you know the exact section/row/seat you are buying prior to purchase, or will you find out later? Many presales don't tell you your seats until after the money is spent, which is not good for the hardcore fan who wants to be in front row. Thanks.
