Had never been to the Tacoma Dome before, but we attended a concert there. It's a huge space, which made me worry about acoustics, but we were pleasantly surprised at how good the sound quality was. The bands were on a stage at one end, but the seating faces into the arena floor area, making you squirm in your seats and risk some neck strain to see the stage. It did have a couple of jumbo-tron screens which helped some, although they were at the stage end of the hall as well.
There were "ushers" outside directing attendees to entrances that didn't have long lines, which we appreciated; and the security and ticketing was efficient and fast. Kudos for that! The hall was surprisingly well ventilated and didn't get overheated, even with a huge crowd. Nice.
The big pain in the wallet is the ridiculous charge they get for parking: $25. That's a rip-off in my book. Private parking lots in the neighborhood are at least that much.
