The new WHL certainly looks great but I'm not too sure the atmosphere will be easy to sustain beyond big games. I say this primarily because in my view there are too many tiers to the side stands. This goes against the transmission of noise between the various sections of fans, particularly as the middle tiers appear to be corporate, as at Wembley and Arsenal. OT has it right, with the corporate areas being at the top of the upper tiers.
I like the huge home end and its proximity to the pitch. But from looking at TV pictures it looks like the seating is not particularly dense, again a negative when needing to generate noise. And one other thing which for me is a no-no -- breaking up the section immediately behind the goal with a gangway.
The "Gangway" you quote is actually two sections roughly either side of the penalty area for wheelchair users and their helpers. Spurs decided that cos people have "disabilities" they should now not be shunted away in corners or not have bad views/away from the atmosphere like they are at many stadiums. This is because facilities have mostly been added in older stadiums where it's easier to build the facilities needed which lets be honest, is a after thought as its only in the last 20? years or so they have really started to be catered for properly.
Surprisingly (and I'm pleased about it,) the seats at WHL are not as wide as at the Emirates and there is maybe a tiny bit less leg room than there is in the equivalent non corporate seats at theirs (but still a lot more than than at old WHL.)
Even though it takes supporters a while to get used to a new stadium, the atmosphere has been quite good, in fact proper rocking for the two of the 5? games so far. The other 3 it's been ok but still proper loud when the big stand gets going (and it actually helps with the atmosphere not having any corporate seats at all at either end of the stadium.)
Oh and also only having the two stands behind each goal at the more reasonable prices for cheaper S/Ts doesn't seem to have ruined the atmosphere and the big stand does generate a massive amount of noise to my end of the stadium (my profile picture was taken from my seat in the middle tier facing the 17,500 stand.)
P.S. I'm not saying that it's perfect as there is still many things for the club to sort out but as there has only been a few games it will take a bit more time to iron things out.
Another thing, don't any of you who visit next week expect to be blown away cos after all, it's just a football stadium (but a very good one.)
