Let's Go Blues

I just purchased ticket, which I may sell for face value, if I can get better ones. The tickets are I got are:

Section 104 - row DD - seats 6 and 5

Whats the DD stand for? The ticketmaster guy said that the seats closest to the ice are in rows with double letters (AA, BB, CC, DD etc.)

So does this mean I am in the 4th from from the ice?

I appreciate any help I can get, thanks!

You are in club seats and I think those are the free food and beer seats but not for sure. You are about 25 rows from the ice, it starts with A then goes to somewhere around T then it goes to BB,CC,DD

The side sections are 101-105 and 114-118.
The rows in the side sections run from "A-W" followed by "AA-HH".
The end sections are 106-113 and 119-126.
The rows in the end sections run from "A-W" followed by "AA-KK".
Entry to each section from the plaza level is at row "R".
Wheelchair or disabled seating is in row "R".
